(1)

No person shall intentionally expose any other person to radiation from any radioactive material or an irradiating apparatus except for medical reasons or other purposes authorised by the terms of a licence.

(2)

Subject to subclause (3), every person who is for the time being in control of any radioactive material or an irradiating apparatus shall take all reasonable steps to ensure that—

(a)

except in the case of exposure to radiation for therapeutic purposes, the dose equivalent received by any person from radiation emanating from the irradiating apparatus or radioactive material is the minimum practicable; and

(b)

except in the case of exposure to radiation for therapeutic purposes or for medical diagnostic purposes or as permitted by the terms of a licence, the dose equivalent referred to in paragraph (a) does not exceed—

(i)

the reference dose equivalent, in the case of persons employed to work with such radioactive material or irradiating apparatus, except that in the case of women of reproductive capacity the dose equivalent shall not exceed one-quarter of the reference dose equivalent in any period of 3 months nor during the period of pregnancy following its diagnosis; or

(ii)

0.1 of the reference dose equivalent, in the case of other persons.

(3)

If the circumstances are such that sufficient protection cannot reasonably be provided so as to fulfil the requirements of subclause (2)(b), the recommendations of the International Commission on Radiological Protection (ICRP Publication 26), shall be followed.

19 Action to be taken in event of over exposure

(1)

Every person who has reason to believe that any person has been exposed to radiation exceeding that permitted under subclause (2), or (where applicable) subclause (3), of regulation 18 shall forthwith report the circumstances to the person who is licensed to use the radioactive material or the irradiating apparatus that gave rise to the exposure, or (if unable to do so) to the Director-General.

(2)

When a licensee has reason to believe that any person has, in any period of 1 year, received from a radioactive material, or from an irradiating apparatus, for which the licensee is responsible irradiation giving a dose equivalent exceeding the reference dose equivalent, he shall forthwith inform that person and the Director-General, and shall supply the Director-General with all pertinent information.

(3)

When such licensee has reason to believe that the dose equivalent referred to in subclause (2) exceeds 10 times the reference dose equivalent, he shall, as soon as he is aware that such exposure can be presumed to have occurred, make available to that person a medical examination performed by an approved medical practitioner, such examination to be primarily for the detection of any effects that might result from such exposure.

(4)

Further medical examination shall be made available to that person at such subsequent times as the approved medical practitioner may advise or the Director-General may require.

(5)

Where the licensee interprets the relevant radiation dose information in accordance with the recommendations of the International Commission on Radiological Protection (ICRP Publication 26) the dose equivalent limits as there defined shall be substituted for the reference dose equivalent.

(6)

On receipt of the information required under subclause (1) or subclause (2), the Director-General may direct that a medical examination be made available to the person so exposed and the licensee shall forthwith comply with that direction.

(7)

Any medical practitioner making an examination pursuant to subclause (3) or subclause (5) shall report the result thereof in writing to the licensee who made the examination available and the person examined, and shall forthwith send a copy of his report to the Director-General.

(8)

The Director-General may appoint a competent person to investigate the circumstances under which any over exposure to radiation is thought to have occurred and to make recommendations as to the prevention of any recurrence.

(9)

Nothing in this regulation shall apply in any case where the dose of radiation—

(a)

is received as a necessary part of medical treatment or diagnosis; and

(b)

is permitted by the terms of a licence—

and is administered by the person licensed to use the radioactive material or the irradiating apparatus from which the dose is derived, or by a person acting under the instructions of that licensee, in accordance with the terms of the licence.

20 Measurement of radiation doses

(1)

Every licensee shall ensure that if he, or any other person acting under the instruction or supervision of the licensee, uses a radioactive material or an irradiating apparatus under conditions in which either he or any such other person could receive in any period of 1 year, by absorption of radiation from sources outside the body, a dose equivalent exceeding 0.3 of the reference dose equivalent, any radiation dose received by either of them while engaged in the use of that radioactive material or that irradiating apparatus shall be continuously measured by means of a dosemeter of a type approved by the Director-General.

(2)

Without limiting subclause (1), every licensee shall, if so required by the Director-General, cause radiation doses received by himself, or by specified persons working under his instructions or supervision with or in the neighbourhood of any source of radiation, or by persons performing specified work under his instructions or supervision, to be measured at such intervals as may be specified, by means of a dosemeter of a type approved by the Director-General.

(3)

Every licensee shall, if so required by the Director-General, ensure that a radiation measuring instrument of a type approved by the Director-General is provided, and used to measure radiation dose rates as often as may be necessary to allow work to be planned so as to satisfy the requirements of subclauses (2) and (3) of regulation 18.

(4)

Every licensee using unsealed radioactive material, or under whose instructions or supervision any other person uses such material, under conditions in which he or that other person could receive, by inhalation or ingestion of radioactive substances contained in such material, an intake during any period of 1 year that would lead to a dose equivalent commitment exceeding 0.3 of the reference dose equivalent shall ensure that an instrument of a type approved by the Director-General is provided and used to make appropriate measurements of levels of radioactive contamination as often as may be necessary to allow work to be planned and carried out so as to satisfy the requirements of subclauses (2) and (3) of regulation 18.

(5)

Without limiting subclause (4), every licensee shall, if so required by the Director-General, ensure that an instrument is provided and used as described in the said subclause (4).

(6)

Subclause (4) shall not apply when the radioactive contamination that would be required to be measured is of a type for the measurement of which no instrument is reasonably obtainable.

(7)

Every person who enters a controlled area shall, before he leaves that area, use the instrument (if any) made available pursuant to subclause (4) or subclause (5) of this regulation for the purpose of detecting any contamination by a radioactive substance on his hands or other part of his body or his clothing, and shall reduce such contamination to an amount estimated by the licensee to satisfy the requirements of regulation 18.

21 Controlled areas

(1)

If a licensee is of the opinion that, by reason of the presence in any place of a radioactive material, or an irradiating apparatus, for which he is responsible, a hazard to any person arises from—

(a)

radiation received from a source outside the body of that person; or

(b)

the possibility of that person ingesting, inhaling, or otherwise absorbing into his body any radioactive substance,—

and that it is necessary, for the purposes of regulation 18, that the area in which the hazard exists (being an area in the occupation or otherwise under the control of the licensee or his employer) should become a controlled area, he shall designate that area as a controlled area.

(2)

Where any area is designated as a controlled area, the licensee, and any other person who uses any radioactive material or any irradiating apparatus in that area knowing that the area is so designated, shall—

(a)

ensure that the area is indicated by warning signs in accordance with clause 5 of Schedule 2; and

(b)

sufficient protective clothing is provided for, and (when necessary for the purposes of regulation 18) worn by all persons working in the controlled area, and that the clothing is removed when such persons leave that area; and

(b)

levels of contamination by radioactive substances are maintained as low as is reasonably possible, and in any case low enough to avoid any contravention of regulation 18.

Part 5 Radiotherapy and diagnosis

22 Radiotherapy records

(1)

Every person who is licensed to use radioactive materials or an irradiating apparatus for therapeutic purposes shall keep a record of the application of such radioactive material, or of radiation from such irradiating apparatus, sufficient to show what parts of the body were irradiated, the quality of the radiation and magnitude of the radiation dose, and relevant data on which the estimate of radiation dose was based.

(2)

The licensee shall retain every record kept by him under subclause (1) for at least 10 years.

23 Restrictions on use of irradiating apparatus in radiotherapy

(1)

No person shall use an irradiating apparatus to administer any beam of radiation for therapeutic purposes to a human being unless the radiation output and the quality of the radiation produced by the particular arrangement and adjustment of the apparatus have been determined by a method approved by the Director-General.

(2)

For the purpose of subclause (1), the expression the particular arrangement and adjustment of the apparatus means—

(a)

where the source is a radioactive material, any combination of source, filter, and source-surface distance; or

(b)

where the source is an X-ray tube, any combination of tube, tube voltage, tube current, filter, and source-surface distance; or

(c)

where the source is any other form of irradiating apparatus, the corresponding parameters.

(3)

The determination of radiation output and the quality of the radiation required under subclause (1) shall be repeated at such intervals as the Director-General may require.

(4)

No person shall use a radiation measuring instrument for the purposes of this regulation unless—

(a)

it is of a type approved by the Director-General; and

(b)

it has been checked for accuracy by a person approved by the Director-General for that purpose; and

(c)

since that check, regular checks have been made that demonstrate that it has retained its accuracy.

(5)

No person shall use any timer in connection with radiation beam therapy unless it complies with subclause (4), and is found to be accurate to within 1% for times greater than 100 seconds, and to within 1 second for shorter times.

(6)

No person shall use an irradiating apparatus to administer any beam of radiation for therapeutic purposes to another person unless the delivered radiation dose is within 5% of the prescribed radiation dose.

24 Special precautions to be taken with irradiating apparatus used in radiotherapy

(1)

Every person using an irradiating apparatus to administer any beam of radiation for therapeutic purposes to another person shall keep that other person and that apparatus under constant supervision.

(2)

No person shall use an irradiating apparatus for any such treatment unless—

(a)

the exposure is controlled by an automatic device that ends the exposure after a predetermined time or predetermined radiation dose and that has been regularly checked by the person licensed to use the apparatus; and

(b)

a warning device of a type approved by the Director-General is provided on the control panel of the apparatus plainly indicating whether or not a beam of radiation is emerging from the apparatus.

(3)

Where an irradiating apparatus generates X-rays using a tube voltage exceeding 150 kV, or is an accelerator of subatomic particles, or is a teletherapy apparatus, a warning device as required by subclause (2)(b) shall be placed at the entrance to the room in which it is used and an interlock system shall be installed so that when any door into the room is open the beam control mechanism automatically shuts off the beam.

(4)

The interlock system shall operate in such a way that it shall not be possible to obtain a beam from the apparatus after it has been automatically shut off except by means of a control at the control panel.

25 Special precautions to be taken with irradiating apparatus used in diagnosis

No person shall use an irradiating apparatus for any diagnostic purpose unless it is fitted with such means of restricting the direction and size of the radiation beam as will ensure that the minimum practicable area of the person examined is irradiated, and is fitted with a filter such as will reduce the radiation dose to that area to the minimum consistent with obtaining the diagnostic information required.

Schedule 1 Activities and concentrations of radioactive materials

rr 2, 4

1 Interpretation

(1)

One becquerel is an activity of 1 transformation per second.

(2)

For the purposes of these regulations, when the transformation of the atoms of a radionuclide gives rise to another radionuclide, the activity is measured by the rate of transformation of the first or “parent” radionuclide only.

(3)

The classification of any radionuclide may, if it is not shown in clause 2 or clause 3, be obtained on application to the Director of the National Radiation Laboratory.

Schedule 2 Labels and warning signs

rr 4, 12, 21

1 Radiation warning symbol

(1)

In this schedule radiation warning symbol means the symbol set out below, subject to such variations as to colour and size as are hereinafter permitted.

graphic of symbol

This is the internationally accepted symbol used to indicate the presence of ionising radiation and radioactive material. The areas shown here as black are also sometimes coloured magenta or purple, and any of the three colourings are acceptable under these regulations except for the labels described in clause 2, for which black must be used. The symbol may be made any size by varying the size of the units of length indicated in the diagram, one unit being one-twentieth of the required diameter.

(2)

Subject to the particular requirements of clauses 2, 3, and 4, a radiation warning symbol may be of any size, each unit of length shown in the symbol set out in subclause (1) being one-twentieth of the required diameter.

2 Labelling of radioactive materials to which regulation 4 applies

(1)

The label required by regulation 4(2)(a)(i) shall bear the radiation warning symbol in black on a white background and, subject to subclause (2) of this clause, it shall have an outer diameter of at least 20 mm. It shall also bear:

(a)

the words “RADIOACTIVE MATERIAL” in letters not less than 3 mm high; and

(b)

the words “Exempt from Radiation Protection legislation except for labelling and manner of disposal when discarded” in letters large enough to be easily legible; and

(c)

a statement of the nature and activity of the radioactive material and the date on which the activity was that so specified.

(2)

Where the outer container is not large enough to bear a label as required by subclause (1), the size of the label may be reduced, but the outer container shall be large enough to bear a label of dimensions one-half of those required by subclause (1).

3 Labelling of containers generally

(1)

Every container, in which radioactive material (other than radioactive material to which regulation 4 applies) is stored or used, shall bear a clearly visible label on each of two opposite sides consisting of the radiation warning symbol, with an outside diameter of not less than 40 mm, together with the words, in lettering at least 5 mm high, “CAUTION—RADIOACTIVE MATERIAL”. Each such container shall also bear a clearly legible label stating the kind of radioactive material in the container, and its activity at a stated time. The colouring of the radiation warning symbol shall be black, magenta, or purple, on a yellow background. If any container of radioactive material is not large enough to bear such a label, it shall be stored in an outer container which bears such a label.

(2)

Nothing in subclause (1) shall apply to containers temporarily holding radioactive materials during laboratory procedures if the area is marked as required by clause 4 or clause 5, as the case may require.

4 Warning signs generally

The warning sign required by subclause (2) of regulation 12 shall be erected at each entrance or door or other point of access to the place in which the radioactive material is stored or used so that it is clearly visible to any person before he can gain access to the radioactive material. The sign shall bear the radiation warning symbol with an overall diameter of not less than 100 mm. Its colour shall be black, magenta, or purple, on a yellow background. The sign shall also bear the words “CAUTION—RADIOACTIVE MATERIAL” in letters at least 5 mm high.

5 Warning signs in controlled areas

At any entrance to, or door of, or other point of access to, a controlled area a sign must be erected in such a manner that it is clearly visible to any person entering or attempting to enter that controlled area. The sign must bear the radiation warning symbol with an overall diameter not less than 100 mm and must be black, magenta, or purple, on a yellow background. The sign must bear in letters not less than 5 mm high the wording “CAUTION—CONTROLLED AREA” and the words “ENTRY PROHIBITED EXCEPT WITH THE AUTHORITY OF (Name or Names of Licensee/Radiation Safety Officer)”.

6 Saving of obligations of licensee, etc

Nothing in the preceding provisions of this schedule shall operate to relieve a licensee, owner, or other person using or possessing a radioactive material or an irradiating apparatus from any obligation imposed on him by these regulations or otherwise by law to give such warnings and advice to any person as will assist that person to avoid or limit his exposure to radiation.
