报道了在室温下适宜于５．４８６ＭｅＶ的α射线的硒镓银晶体核辐射探测器的制备及其性能测试结果．１０ｍｍ×７ｍｍ×０．６ｍｍ的硒镓银晶片被磨平、抛光和清洁后，在其两面镀上电极．硒镓银探测器在室温下用２４１Ａｍ源发出的５．４８６ＭｅＶα射线进行辐射测试．结果表明，硒镓银晶体是一种有希望的室温α射线探测器新材料．
The preparation of selenium-gallium-silver-crystal nuclear radiation detector suitable for α-ray of 5.486 MeV at room temperature and the results of its performance test were reported. Selenium gallium-silver chips of 10 mm × 7 mm × 0.6 mm were polished, polished and cleaned, and plated with electrodes on both sides. Selenium gallium detector was irradiated with 5.486 MeV alpha radiation from a 241 Am source at room temperature. The results show that selenium gallium silver crystal is a promising room temperature α-ray detector new material.
