Researches of alpha and beta radioactivity at long-term observations

摘要: The part of results obtained on multichannel installation created for researches various processes, including alpha and beta decays, in a combination to recording environment parameters, is represented. works more than 13 years practically continuously. At the count rate measurements Co-60 Sr-90 Y-90 sources rhythmic changes with amplitude 0.3 % from average magnitude period 1 year, up 0.02 about one month are detected. Count Pu-239 not by us compared similar other researchers. argumentation critics analyzed.
