skos:definition "1. Material designated in national law or by a 'regulatory body' as being <br/>
subject to 'regulatory control' because of its 'radioactivity'.<br/>
<b>!</b> 'Radioactive material' should be used in the singular unless reference is <br/>
expressly being made to the presence of various types of 'radioactive material'.<br/>Some States use the term <i><b>radioactive substance</b></i> for this regulatory purpose. <br/>However, the term 'radioactive substance' is also sometimes used to indicate <br/>that the scientific use of 'radioactive' (see 'radioactive' (1)) is intended, rather <br/>than the regulatory meaning of 'radioactive' (see 'radioactive' (2)) suggested by <br/>the term 'radioactive' 'material'. It is therefore essential that any such <br/>distinctions in meaning are clarified.<br/>In regulatory terminology in some States, 'radioactive material' ceases to be <br/>'radioactive material' when it becomes 'radioactive waste'; the term <i>radioactive <br/>substance</i> is used to cover both, i.e. 'radioactive substance' includes <i>radioactive <br/>material</i> and 'radioactive waste'.<br/>
2. Any material containing radionuclides where both the 'activity '<br/>
'concentration' and the total 'activity' in the 'consignment' exceed the values <br/>specified in paras 401–406 [of the Transport Regulations]. (From Ref. [2].)<br/>
<b>!</b> This usage is specific to the Transport Regulations, and should otherwise be <br/>
avoided.<br/>" (en)
