摘要

从尼日利亚中北部的商业农田中采集了薯蓣块茎（Dioscorea rotundata）和土壤，并使用3“×3”NaI（Tl）伽马探测器对其天然放射性含量进行了调查。土壤中238U、232Th和40K的平均活度分别为38.13±3.76 Bq kg~（-1）、15.06±0.99 Bq kg_（-1）和381.80±15.50 Bq kg。结果与世界可接受的安全水平一致。对238U、232Th和40K测定的活性范围分别为BDL-76.68±9.73 Bq kg-1、BDL-19.77±1.30 Bq kg-1和312.50±20.73-627.94±38.37 Bq kg-，平均值分别为29.23±4.0、13.10±0.72和445.10±27.20 Bq kg~（-1）。从摄入yam摄入放射性核素的总有效剂量在272.12μSv y-1和935.97μSv y-1之间波动。相关分析表明，238U和232Th是摄入尼日利亚中北部种植的红薯总有效剂量的主要贡献者。

ANNUAL EFFECTIVE DOSE ESTIMATION DUE TO THE NATURAL RADIOACTIVITY IN YAM TUBERS (Dioscorea rotundata) CULTIVATED IN NORTHCENTRAL NIGERIA

Yam tubers (Dioscorea rotundata) and soil from commercially cultivated farmland in northcentral Nigeria were collected and investigated for their natural radioactivity content using a 3” × 3” NaI(Tl) gamma detector. Average activities of 238U, 232Th and 40K in the investigated farm soil were 38.13±3.76 Bq kg-1, 15.06±0.99 Bq kg-1 and 381.80±15.50 Bq kg-1, respectively. The results agree with the world’s acceptable levels of safety. Activities measured in the yam tubers were in the range from BDL -76.68±9.73 Bq kg-1 for 238U, BDL - 19.77±1.30 Bq kg-1 for 232Th and 312.50±20.73 - 627.94±38.37 Bq kg-1 for 40K, with average values of 29.23±4.0, 13.10±0.72 and 445.10±27.20 Bq kg-1, respectively. The total effective dose from radionuclide intake from yam ingestion fluctuated between 272.12 μSv y-1 and 935.97 μSv y-1. Correlation analysis identified 238U and 232Th as the leading contributors to the total effective dose from ingesting yam tubers cultivated in northcentral Nigeria.
