秦山核电基地外围植被中14C水平分布研究OA北大核心CSCDCSTPCD
Terrestrial Distribution of 14C in Vicinity of Qinshan Nuclear Power Plant
为了解秦山核电基地外围14C的水平分布与规律,本文采用加速器质谱法(AMS)对秦山核电基地外围6.5 km以内的植物样品(苔藓、松针)与食物样品中的14C比活度进行测量.测量结果显示:苔藓样品的14C比活度范围为223.0～265.6 Bq/kg C(本底为223.8 Bq/kg C),14C比活度随距排放点距离的增加呈降低的趋势,在距排放源6.5 km处达到了本底水平.与松针相比,苔藓更适合做核设施14C排放的指示植物.苔藓样品的14C比活度分…查看全部>>
To study the 14C levels in the food samples and botanic samples (moss and pine needle) which were distributed in the radius of 6. 5 kilometer, 14C specific activity was measured using accelerator mass spectrometry (AMS). The 14C specific activity in moss samples, which ranges from 223. 0 to 265. 6 Bq/kg C, decreases with increasing of the distance from the stacks of Plant m (heavy water reactor) and reaches to the background (223. 8 Bq/kg C) at a distance of…查看全部>>
