Burial limits for radioactive waste

The expanding population necessitates a re-examination of the earlier practice of shallow earth burial of low-level radioactive solids in government-controlled land. In this regard, some official guidelines for radiation dose limits are reconsidered. Some major release mechanisms and pathways of radionuclides are discussed with the use of a model burial ground 1000 m on a side and 10 m deep lying over an aquifer with a velocity of 30 cm/day. The effect of intrusion by vandals and others is assessed. 6 refs
