Abstract
Responses from one manual and four automatic gamma counters for assaying (125)I were compared. The resolution times quoted by manufacturers when applied in a standardized correction formula to obtain true counts from observed counting rates above 10(4) counts per second appeared to be inadequate. The need to investigate the errors associated with high counting rates for all instruments and electronic settings employed to determine (125)I in radioimmunoassays is emphasized.
摘要
比较了一台手动γ计数器和四台自动γ计数器对（125）I的测定结果。制造商给出的分辨率时间，当应用于标准化校正公式以从高于每秒10（4）次计数的观测计数率中获得真实计数时，似乎并不足够。强调了对用于放射免疫分析中测定（125）I的所有仪器和电子设置，研究与高计数率相关误差的必要性。
