摘要
滨医附院ECT室周围的电离辐射污染监测与调查分析表明:现役ECT工作场所γ空气吸收剂量率基本处于天然放射性本底水平,ECT室的辐射防护设施设计是合理的,具有重要的现实意义,该辐射防护设施具有推广价值。
Through the monitoring investigation on the ionizing radiation of ECT lab in hospitals to the surrounding environment,the result is lower than the standard limit level of 'basic standards for protection against ionizing radiation and for the safety of radiation sources'(GB18871-2002).It indicates that the air absorb dose rate of γ-ray is mostly equal to the natural level on the whole,and it indicates that the protective designing for radiation of ECT lab is safe and reasonable.This facility has important realistic meaning and the value of popularizing.
