【摘要】用22Na研究植物示踪的液体计数法,建立了一个在植物同位素示踪法中有效测量放射性同位素的方法。研究了不同的样品制备、闪烁液用量、植物含水量、化学淬灭等因素对测量的影响,同时在测量时引入离心小管,降低实验成本,使实验简单可靠。更多还原

【Abstract】 A new experimental means which measured radioactive count on 22Na plant tracing was found.Some factors influencing on count which included different sample disposals,water content of plant,dosage of twinkle liquid,and chemistry quenching were studied.And small centrifugal tubes were used in experiment.The tube can reduce the cost,and make the experiment simple and reliable.更多还原
