Technical Services Group NOT PROTECTIVELY MARKED Reference: TSG(09)0488 Issue: Issue 2 Date: 15 th July 2009 CALCULATION OF DOSE RATE AT LANDFILL IN SUPPORT OF A LOW LEVEL WASTE DISPOSAL AUTHORISATION UK-10497 SUMMARY Dose rate calculations were performed in MicroShield to support a low level waste disposal authorisation. An estimate of the dose rate at the landfill site was calculated based on lightly-contaminated rubble being covered by a 30 cm layer of soil material. Dose was found to dependant on the soil material density and largely independent on the distance from the source.
