Radioactive material, low specific activity LSA

RADIOACTIVE MATERIAL, LOW SPECIFIC ACTIVITY (LSA-I) non-fissile or fissile-excepted ... 

Of special importance are Low specific activity (LSA) materials. LSA is radioactive material which by its nature has a hmited specific activity, or radioactive material for which hmits of estimated average specific activity apply. External shielding materials surrounding the LSA material shall not be considered in determining the estimated average specific activity. 

Less dangerous radioactive materials permit less stringent packages. Specifically, Industrial Package Types 7, 2, and 3 are in use for low-specific activity (LSA) materials and surface-contaminated objects (SCO) ... 

Radioactive materials are grouped according to their form and/or characteristics. These include Special Form Low Specific Activity (LSA) Surface Contaminated Object (SCO) Fissile Other Form. A radioactive material may meet the definition of one or more of the above. lATA 10.3.3... 

LSA material is that which has by its nature a limited specific activity. It is divided into three groups (1) LSA-I includes ores or naturally occurring radionuclides, unirradiated natural or depleted uranium, and other low activity radioactive materials (2) LSA-II includes certain concentrations of tritium and solids, liquids, and gases with no more than 10,000 to 100,000 times less activity than A2 per gram and (3) LSA-III includes solid materials that are imbedded in a binder, relatively insoluble, and with not more than 500 times less activity than A2 per gram.
