在放射源生产中,由于放射源的活度很高,量热计是一种方便有效的活度直接测量方法,在国内外得到广泛使用。量热计的原理是放射源在一定时间t内放出的射线能量的总和E除以它放出的射线的平均能量
In the production of radioactive sources, due to the high activity of radioactive sources, calorimeters are a convenient and effective method for direct measurement of activity and are widely used both at home and abroad. The principle of a calorimeter is the sum of the energy of the rays emitted by the source over a certain period of time t divided by the average energy of the rays it emits
