Radiation Protection Regulations 1982

Schedule 3
Exempted articles

r 4(3)

Part 1

Description of article Conditions of exemption

  • 1 Clocks, watches, and other instruments containing luminous material activated by radium–226, promethium–147, nickel–63, carbon–14, or hydrogen–3, of activity not exceeding twice the activity shown in the first column of the table in clause 2 of Schedule 1 for the group in which the radionuclide appears in the second column of that table.

 

  • 1 The radioactive material shall be effectively covered to prevent accidental ingestion or inhalation.

  • 2 Clocks, watches, and other instruments not intended to be used for domestic purposes or to be worn or carried on any part of the body, otherwise than for special purposes likely to involve such wearing or carriage for no more than 1 000 hours in any year, and containing luminous material activated by radium–226, promethium–147, nickel–63, carbon–14, or hydrogen–3, of activity not exceeding 15 times the activity shown in the first column of the table in clause 2 of Schedule 1 for the group in which the radionuclide appears in the second column of that table.

 

  • 2(a) The radioactive material shall be effectively covered to prevent accidental ingestion or inhalation.

  • (b) The instrument shall be prominently and durably marked, on the dial or externally, with the symbol for the radionuclide, or for the element of which that radionuclide is an isotope, and with an indication of the activity present.

  • 3 Smoke detecting fire alarms and other atmospheric contaminant detectors containing any alpha-emitting radionuclide of activity not more than 100 times the activity shown in the first column of the table in clause 2 of Schedule 1 for the group in which the radionuclide appears in the second column of that table.

 

  • 3(a) The radioactive material shall be in a form which effectively prevents its dispersal, and shall be mounted in such a manner that it is not readily accessible without dismantling the apparatus.

  • (b) The device shall bear a durable label containing the radiation warning symbol set out in clause 1 of Schedule 2, in black on a white background and with an overall diameter of not less than 20 mm, together with the words, in letters not less than 3 mm high, “CONTAINS RADIOACTIVE MATERIAL—DO NOT DISMANTLE”, or other adequate warning which has been approved by the Director-General.

  • (c) The device is accompanied by written instructions, which have been approved by the Director-General, in regard to the care, safe use, and ultimate means of disposal, of the radioactive material.

Part 2

Description of article Conditions of exemption

  • 1 Ionisation and electron capture detectors for use in gas chromatography and similar equipment, containing not more than 500 megabecquerels of Nickel–63 or 10 gigabecquerels of Hydrogen–3 (Tritium).

 

  • 1 That part of the detector containing the radioactive material shall bear a label as described in clause 2 of Schedule 2.

  • 2 Luminous devices activated by Hydrogen–3 (Tritium) in the form of elementary hydrogen gas with not more than 1 gigabecquerel in any other chemical form and of total activity not exceeding 100 gigabecquerels.

 

  • 2 The device is accompanied by written instructions, which have been approved by the Director-General, in regard to the care, safe use, and ultimate means of disposal, of the radioactive material.

  • 3 Uranium metal of natural isotopic composition, or depleted in Uranium–235, which is used as radiation shielding, either in transport packages for radioactive materials or in any other manner.

 

  • 3 The uranium metal shall be completely clad in a sheath of metal which is not radioactive and which will effectively protect the uranium metal from mechanical or chemical damage in its intended use.
