The isotopic composition of several spent smoke detectors containing plutonium has been investigated. The article also presents the calculated results of ²⁴¹Am and ²⁴¹Pu activities in smoke detectors. The received values vary from (0.934±0.028) MBq to (91.2±4.6) MBq. The eguivalent dose rate of the established gamma radiation vary from 220 nSv/h to 500 nSv/h. A dose caused by artificial radionuclides in spent smoke detectors was evaluated and compared in the article. It has been found out that due to smoke detectors, an annual dose varies from 0.06 mSv to 0.31 mSv.
