摘要
溶液中的α-活性物质用钛凝胶或硫酸钡载带,掺入ZnS(Ag)内制成样品源,并将此样品源密封后放到光电倍增管下测量,探测效率～0.95(4π)。对含射气样品的测量具有显著优点。
The Alpha active substances were absorbed from the solution by Ba^(2+) onTi^(4+) and then mixed evenly with ZnS(Ag), the precipitate was filtrated, driedsealed and measured in equipment with a photomultiplier. The detection angle is4π, the efficiency is～0. 95. This method can quntitatively detect ^(222)Rn, ^(220)Rn,and their daughters.
