用小立体角法测定α放射性样品质量

Determine α radioactive sample quality with small solid angle law

放射性样品的质量可用小立体角装置绝对测量α计数,从而可以推出样品的质量.样品质量的测量精度主要依赖于小立体角装置的几何,而刻度小立体角装置的几何因子有两个方法即放射性法和几何方法.

The quality of the radioactive sample can be measured and α count definitely with small solid angle device,thus to put out the quality of sample.The precision of measurement of the quality of the sample depends on geometry of the small solid angle device mainly,and there are two methods to scale the geometry factor of the small solid angle device,namely radioactive laws and geometry method.
