Abstract

Gamma-ray scintillation spectrometry has been used to measure the 137Cs and 134Cs levels and depth distributions in soil of a tea plantation in the Eastern Black Sea region in Turkey. Soil samples were collected in November 1987. The depth distribution was found to be exponential with alpha = 0.16 cm-1 and the exposure rate arising therefrom is calculated as 17.46 mu R/h over ground surface.

摘要

γ射线闪烁光谱法已被用于测量土耳其黑海东部地区一个茶园土壤中的¹³⁷Cs和¹³⁴Cs含量及深度分布。土壤样本于1987年11月采集。发现深度分布呈指数关系，α = 0.16 cm⁻¹，由此计算出地面上方的照射率为17.46 μR/h。
