(4) No person shall convey, or cause or permit to be conveyed, any radioactive substance on any vehicle unless there be conspicuously displayed at the front and rear thereof notices in English and Chinese indicating the presence of such substance.
(5) No person shall convey, or cause or permit to be conveyed. any radioactive substance in any vehicle or vessel except under the supervision of the owner, consignor or consignee of the substance or bis representative authorized in that behalf.
(6) No person shall convey, or cause or permit to be conveyed, any passengers other than the crew of the vehicle or vessel and the owner, consignor or consignee or any representative thereof authorized in that behalf, in any vehicle or vessel which is conveying radioactive material; and no person shall cause or permit any member of the crew of such vehicle or vessel to be in the same compartment thereof as that in which the radioactive material is conveyed or otherwise pearet to such material than the distance specified in the Table to paragraph (2) of regulation 6.
(7) No person shall convey, or cause or permit to be conveyed, (L.N. 15/64). any goods classified in the Dangerous Goods (Classification) Regulations 1964, as being dangerous goods in the same vehicle or vessel as that in which any radioactive substance is conveyed unless such dangerous goods are themselves radioactive substances.
(8) Any person who contravenes any of the provisions of— (4) paragraph (1) or (2) shall be guilty of an offence and liable on summary conviction to a fine of five thousand dollars; and (b) paragraph (4), (5), (6) or (7) shall be guilty of an offence and liable on summary conviction to a fine of two thousand dollars,
6. (1) No person shall store in any one place a greater number Storage. of containers containing any radioactive substance and bearing White or Yellow Labels, as referred to in regulation 4, than forty or such lesser number of containers that the total number of radiation units indicated on such labels does not exceed forty units:
Provided that the Authority may grant, subject to such conditions as it may think fit to impose, permission in writing for this number of containers or radiation units, as the case may be, to be exceeded in any particular case where the Authority is satisfied that adequate safety precautions exist.
(2) No person shall store, or cause or permit to be stored, any container containing any radioactive substance and bearing a Yellow Label, as referred to in regulation 4, nearer to any area which is used for living accommodation or as regularly occupied working space than the distance, measured in any direction, specified in the Table to this paragraph appropriate to the number of radiation units specified therefor.

(3) For the purposes of the Table to paragraph
(a) column A applies where there are no intervening goods, walls or other material of not less than the density of water situated between the container containing the radioactive substance and the living accommodation or working space in question:
(6) column B applies where there is situated not less than two feet of goods or other material of not less than the density of water and at least one partition composed of sheet steel of not less than one half inch in thickness, or the equivalent in density thereto if composed of other material, between the container containing the radioactive substance and the living accommoda- tion or working space in question:
(c) column C applies where there is situated not less than six feet and seven inches of goods or other material of not less than the density of water and at least two partitions composed of
