~(241)Am感烟探测源是火灾报警器的核心部件,报警器的可靠性不仅决定于源的表面粒子数,而且决定于α粒子的能量。不同厂家生产的报警器对α粒子能量高低要求不同,生产放射源的单位可采用活性区上不同金覆盖层厚度来确定戋射的α粒子能量。为了
~ (241) Am smoke detection source is the core of the fire alarm. The reliability of the alarm depends not only on the number of particles on the surface of the source, but also on the energy of the alpha particle. Alarms produced by different manufacturers have different requirements on the energy level of alpha particles. Units that produce radioactive sources can use different gold coating thicknesses on the active zone to determine the emitted alpha particle energy. in order to
