EFFECTS OF GROUND ROUGHNESS ON THE $gamma$ DOSE FROM CS$sup 137$ CONTAMINATION
Technical Report
·
OSTI ID:4089965
The effects of ground roughness on the dose observed above a contaminated field were measured with Cs/sup 137/ sources and a concrete ground with a 45 degree sawtooth profile of 6 in. depth. The effect of rough ground was to reduce the dose observed at a height of 1 meter by a factor that varied markedly with the choice of ground roughness and with distribution of contamination. The results indicate that failure to allow for ground roughness could be the main source of error in the determination of radiation hazards near ground level from the aerial survey of a contaminated region.
