Air humidity and annual oscillations in ⁹⁰Sr/⁹⁰Y and ⁶⁰Co decay rate measurements

RADIOACTIVITY ⁹⁰Sr, ⁹⁰Y, ⁶⁰Co(β^-); analyzed available data; deduced environmental conditions in the Moscow area at the time of the experiment appears to be resemble the shape of the annual ⁹⁰Sr/⁹⁰Y decay rate anomalies with the inverse of the absolute air humidity, albeit with an apparent time shift of 0.05-0.15 year, the instabilities in the ⁶⁰Co data were more difficult to correlate with environmental data, except for some similarities with temperature and external dew point.
