Exemption from registration 3 1 Subject to paragraph (3) below and the conditions specified in Schedule 1 to this Order, a person using premises as a hospital is exempted from registration under section 1 of the Act in respect of those premises in relation to the keeping and use on those premises of radioactive material to which paragraph (2) below applies which is kept or used on the premises for the purposes of medical diagnosis, treatment of patients or supply to another hospital. 2 This paragraph applies to radioactive material which is solid or liquid, contains no alpha emitters and, in the case of solid material, is not a closed source. 3 Paragraph (1) does not apply where a registration under section 1 of the Act is in force in respect of the premises. Exclusion for certain disposals 4 1 Subject to paragraph (2) below and the conditions specified in Schedule 2 to this Order, radioactive waste arising on hospital premises is excluded from the provisions of section 6(1) of the Act if it is solid or liquid waste, contains no alpha emitters and— a immediately before it became waste it was radioactive material to which article 3(2) above applies; or b it is a substance or an article which is radioactive solely because it has been contaminated in the course of the keeping or use of radioactive material on those premises for the purposes of medical diagnosis, treatment of patients or supply to another hospital or by contact with or proximity to other waste falling within this paragraph; or c it is human excreta; or d it is residual ash (including cinders and other debris) produced by the burning of other waste falling within this paragraph. 2 Paragraph (1) does not apply where an authorisation under section 6(1) of the Act is in force in respect of the disposal of radioactive waste on or from the premises. 3 Radioactive waste to which paragraph (1) above applies is excluded from section 6(3)of the Act if— a it is solid waste and it has been removed from the premises by a person other than a waste collection authority for disposal at the same place as substantial quantities of non-radioactive waste in or on land subject to a site licence; or b it is solid waste and it has been removed from the premises by a waste collection authority; or c it is solid waste or flammable liquid waste and it has been removed from the premises by a person other than a waste collection authority for disposal by burning on other hospital premises, subject to the condition that it is disposed of by burning on those other premises in compliance with paragraph 5 of Schedule 2 to this Order. Exclusion for certain accumulations 5 1 Radioactive waste to which article 4(1) above applies is excluded from the provisions of section 7(1) of the Act if it is kept in a closed container on hospital premises and it is disposed of within a period of two weeks beginning with the date upon which the waste arises. 2 Radioactive waste which has been removed from hospital premises in accordance with article 4(3) above is excluded from the provisions of section 7(1) of the Act subject to the condition that it is disposed of as soon as practicable after its removal.
