skos:definition "<b>!</b> This usage is specific to the Transport Regulations, and should otherwise be <br/>
avoided.<br/>
'Radioactive material' which by its nature has a limited 'specific activity', or <br/>
'radioactive material' for which 'limits' of estimated average 'specific activity' apply. <br/>External shielding materials surrounding the 'low specific activity material' shall <br/>not be considered in determining the estimated average 'specific activity'.<br/>
'Low specific activity material' shall be [classified] in one of three groups:<br/>
(a)<br/>
<i><b>LSA-I</b></i><br/>
1. Uranium and thorium ores and concentrates of such ores, and other <br/>
ores containing 'naturally occurring radionuclides' which are intended <br/>to be processed for the use of these radionuclides;<br/>
2. 'Natural uranium', 'depleted uranium', natural thorium or their <br/>
compounds or mixtures, provided that they are unirradiated and in <br/>solid or liquid form;<br/>
3. 'Radioactive material' for which the 'A ' value is unlimited, excluding <br/>
'2'<br/>
'fissile material' in quantities not excepted under para. 672 [of Ref. [2]]; <br/>or<br/>
4. Other 'radioactive material' in which the 'activity' is distributed <br/>
throughout and the estimated average 'specific activity' does not <br/>exceed 30 times the values for 'activity concentration' specified in paras <br/>401–406 [of Ref. [2]], excluding 'fissile material' in quantities not <br/>excepted under para. 672 [of Ref. [2]].<br/>
(b)<br/>
<i><b>LSA-II</b></i><br/>
1. Water with tritium concentration up to 0.8 TBq/L; or<br/>
2. Other material in which the 'activity' is distributed throughout and the <br/>
estimated average 'specific activity' does not exceed 10–4 'A '/g for solids <br/>
'2'<br/>
and gases, and 10–5 'A '/g for liquids.<br/>
'2'<br/>
(c)<br/>
<i><b>LSA-III</b></i><br/>
Solids (e.g. consolidated 'waste', activated material), excluding powders, in <br/>
which:<br/>
1. The 'radioactive material' is distributed throughout a solid or a <br/>
collection of solid objects, or is essentially uniformly distributed in a <br/>solid compact binding agent (such as concrete, bitumen, ceramic, <br/>etc.);<br/>
2. The 'radioactive material' is relatively insoluble, or is intrinsically <br/>
contained in a relatively insoluble matrix, so that, even under loss of <br/>'packaging', the loss of 'radioactive material' per 'package' by leaching <br/>when placed in water for seven days would not exceed 0.1 'A '; and<br/>
'2'<br/>
3. The estimated average 'specific activity' of the solid, excluding any <br/>
shielding material, does not exceed 2 × 10–3 'A '/g. (From Ref. [2].)<br/>
