分别对室内及室外环境进行累积剂量测量和瞬时剂量率测量，并对测量结果进行比对分析。比对结果表明，室内累积剂量测量与瞬时剂量率测量En≤1，比对结果为满意；2013年北京市环境累积剂量率与瞬时剂量率测量结果相对偏差＜30％，比对结果为满意。本次比对在一定程度上验证了累积剂量测量系统和瞬时剂量测量仪器这两类不同原理的剂量监测仪器测量结果的可靠性。%Measurements of the cumulative dose and instantaneous dose rate of indoor and outdoor environment respectively are done and the results are compared.The results indicate that the value of En for the cumulative dose and instantaneous dose rate of indoor is less than or equal to 1,so that the result is satisfactory;The rela-tive deviation of cumulative dose rate and the instantaneous dose rate for Beijing environment in 2013 is less than 30%, so the comparison result is satisfactory too.This comparison, to some extent, verify the reliability of the measurement results based on two different principle for radiactive dose monitoring instruments, one for cu-mulative dose measurement system, the other for the instantaneous dose measurement instrument.
