Abstract
Fallout 137Cs levels in soil were measured at 11 diverse sites throughout Montana. Concentrations in near-surface samples ranged from 20–200 mBq g−1 (0.51–5.41 pCi g−1). Most of the 137Cs was in the top 10 cm of soil. Deeper occurrences were attributed to disturbances by animals and to interstitial flow of small sediment particles within saturated soils. The areal concentrations ranged from 130–748 mBq cm−2 (3.6–20.2 pCi cm−2) and were highly correlated with annual precipitation.This publication has 2 references indexed in Scilit:
