摘要
依据国家标准建立了用于校准β剂量(率)仪和计量计并确定其能量响应的β参考辐射。在其刻度位置上的β剂量率,用外推室系统进行了定度和验证。
A system of beta reference radiation,which meets the requirement of national standard setsup. The system is used for calibrating beta doseratermeters or dosimeters and for determiningtheir response as a function of beta energy. The dose rate produced by the reference radiation at agiven place is measured and verified using an extrapolation chamber system,which is exeminedand approved as the first class metrological standard by the competent authority,The details men-tioned above are introduced and discussed in the paper.
