Influence of some factors on alpha energy spectrum of ²⁴¹Am fire alarm source

Influence of some factors on alpha energy spectrum of 241 Am fire alarm source 1 first-author 1 1 China Institute of Atomic Energy, Beijing 102413 China Institute of Atomic Energy, Beijing 102413 Several primary factors influencing the alpha energy spectrum of 241 Am fire alarm source have been studied in order to get better alpha energy spectrum. The results show that the homogeneity and the thickness of metal surface coat and the size of active area of the source have considerable influence on the alpha energy spectrum of the source. 241 Am fire alarm source Alpha energy spectrum Full width at half maximum References FENG Gensheng , WANG Ying , FENG Xinzhan .
