用盖革4π法和固定立体角法对Sr~(90)+Y~(90)β~-放射源的放射性强度进行了绝对测量,对源的制备和测量装置作了某些考虑,对一些影响因素作了校正。两种方法的测量结果在5%以内符合。
The radiometric intensities of Sr ~ (90) + Y ~ (90) β ~ - radioactive sources were measured absolutely by Gegege 4π method and fixed solid angle method, some considerations were made for the source preparation and measuring device. For some Corrected factors were corrected. The measurement results of the two methods are within 5%.
