随着原子能在农业上的广泛应用,强辐射源不断地在各地建成,为了更好地发挥其作用,照射剂量场的标定工作更显重要。剂量测量方法通常有。(1)电离型剂量仪测量;(2)硫酸亚铁或硫酸铈等测量。我们采用电离型剂量仪作为剂量场的标定方法,操作简单、容易掌握,只要严格控制实验条件,测量数据准确可靠。测量条件1.辐射室为水泥结构,空心圆柱体,国产~(60)Coγ源,每根1000克镭当量,两根串联在
With the widespread application of atomic energy in agriculture, intense radiation sources are continuously built in various places. In order to play its role better, the calibration of irradiation dose field is even more important. Dosimetry methods are usually available. (1) ionization type dosimeter measurement; (2) ferrous sulfate or cerium sulfate measurement. We use the ionization type dosimeter as the calibration method of the dose field, which is easy to operate and easy to master. As long as the experimental conditions are strictly controlled, the measurement data is accurate and reliable. Measurement conditions 1. Radiation chamber for the cement structure, hollow cylinder, made ~ (60) Coγ source, each 1000 grams radium equivalent, two in series
