Handle probe and counting system for radiophosphorus test can be checked by the use of a 64 nCi Strontium-90 radiator established inside a plexiglas cylinder. Counting system adjustment to 40 dB amplifier and 0.70 discriminator resulted in 1710cpm+/-2% standard deviation. This check method is suitable for controlling the counting system before tumor measurement. Advantages of this test method are low expenses, stability of the radionuclide, and riskless use of beta-radiator.
用于放射性磷测试的探头和计数系统可以通过使用置于有机玻璃圆柱体内的64纳居里锶-90辐射源进行检查。将计数系统调整至40分贝放大器和0.70甄别器，得到的标准偏差为1710次每分钟计数±2%。这种检查方法适用于在肿瘤测量前对计数系统进行控制。该测试方法的优点是费用低、放射性核素稳定以及使用β辐射源无风险。
