摘要

建立了东罗多佩未勘探地区土壤中自然辐射背景的局部值。评估了人为活动作为辐射背景增加的潜在风险的影响。分析了已清理的铅锌矿附近地区的土壤样本——Madzharovo、金矿——Ada Tepe、Krumovgrad、铅锌复合体——Kardzhali、Neochim——Dimitrovgrad、用于提取片麻岩的矿床、大理石采石场等，以研究可能的污染。用DSA 1000多通道分析仪进行伽马能谱分析，生产CANBERRA和HPGe探测器，测定了研究样品中天然放射性核素210Pb、238U、226Ra、235U、232Th、40K和工艺成因137Cs的比活度。

Radiation status of soils from the region of the Eastern Rhodopes (Southern Bulgaria)

Local values of natural radiation background in soils from unexplored regions in the Eastern Rhodopes were established. The impact of anthropogenic activity as a potential risk for increase in radiation background was assessed. Soil samples from areas near the liquidated lead-zinc mines – Madzharovo, gold mine – Ada Tepe, Krumovgrad, lead-zinc complex – Kardzhali, Neochim – Dimitrovgrad, deposits for extraction of gneiss, marble quarries, etc. were analyzed to study possible contamination. Specific activity of natural radionuclides 210Pb, 238U, 226Ra, 235U, 232Th, 40K and technogenic 137Cs in the studied samples was determined by gamma spectrometric analysis with Multichannel analyzer DSA 1000, production of CANBERRA and HPGe-detector.
