### sec.7 Security enhanced source— Act , sch 2 For schedule 2 of the Act , definition security enhanced source , each of the following radiation sources is prescribed to be a security enhanced source— a sealed radioactive substance that has a security category of 1, 2 or 3; an aggregation of sealed radioactive substances that has a security category of 1, 2 or 3. For subsection (1) , the security category of a sealed radioactive substance, or of an aggregation of sealed radioactive substances, is the security category stated in schedule 2 , part 1 opposite the activity ratio of the substance or aggregation as worked out under subsection (3) or (4) . For subsection (2) , the activity ratio of a sealed radioactive substance is worked out using the formula— where— A means the activity of the radionuclide in the sealed radioactive substance, stated in gigabecquerels. AR means the activity ratio. RAV means the radionuclide activity value stated in schedule 2 , part 2 for the radionuclide in the sealed radioactive substance. For subsection (2) , the activity ratio of an aggregation of 2 or more sealed radioactive substances is the sum of the activity ratios of each of the sealed radioactive substances in the aggregation worked out under subsection (3) . (sec.7-ssec.1) For schedule 2 of the Act , definition security enhanced source , each of the following radiation sources is prescribed to be a security enhanced source— a sealed radioactive substance that has a security category of 1, 2 or 3; an aggregation of sealed radioactive substances that has a security category of 1, 2 or 3. (sec.7-ssec.2) For subsection (1) , the security category of a sealed radioactive substance, or of an aggregation of sealed radioactive substances, is the security category stated in schedule 2 , part 1 opposite the activity ratio of the substance or aggregation as worked out under subsection (3) or (4) . (sec.7-ssec.3) For subsection (2) , the activity ratio of a sealed radioactive substance is worked out using the formula— where— A means the activity of the radionuclide in the sealed radioactive substance, stated in gigabecquerels. AR means the activity ratio. RAV means the radionuclide activity value stated in schedule 2 , part 2 for the radionuclide in the sealed radioactive substance. (sec.7-ssec.4) For subsection (2) , the activity ratio of an aggregation of 2 or more sealed radioactive substances is the sum of the activity ratios of each of the sealed radioactive substances in the aggregation worked out under subsection (3) . - (a) a sealed radioactive substance that has a security category of 1, 2 or 3; - (b) an aggregation of sealed radioactive substances that has a security category of 1, 2 or 3.
