Parkhomov published decay rate measurements of Sr/Y and Co beta decay sources with Geiger-Müller counters which showed annual cyclic deviations with less than 0.2% amplitude from a purely exponential slope. He investigated instrument instability induced by environmental parameters, yet did not find a clear coincidence with local temperature, atmospheric pressure, and relative humidity. Parkhomov hypothesised that gravitationally-focussed 'slow' cosmic neutrinos influenced beta decay. In the current work, environmental conditions in the Moscow area at the time of the experiment are presented. There appears to be a resemblance of the shape of the annual Sr/Y decay rate anomalies with the inverse of the absolute air humidity, albeit with an apparent time shift of 0.05-0.15 year. Humidity may have influenced the range of beta particles in air, as well as geometric and electronic properties of the detection set-up, however causality could not be unambiguously demonstrated. The instabilities in the Co data were more difficult to correlate with environmental data, except for some similarities with temperature and external dew point.
帕尔霍莫夫发表了使用盖革 - 米勒计数器对锶/钇和钴β衰变源衰变率的测量结果，这些结果显示出年度周期性偏差，与纯指数斜率的偏差幅度小于0.2%。他研究了环境参数引起的仪器不稳定性，但未发现与当地温度、大气压力和相对湿度有明显的相关性。帕尔霍莫夫推测，引力聚焦的“慢”宇宙中微子影响了β衰变。在当前工作中，展示了实验期间莫斯科地区的环境条件。年度锶/钇衰变率异常的形状似乎与绝对空气湿度的倒数相似，尽管存在0.05 - 0.15年的明显时间偏移。湿度可能影响了β粒子在空气中的射程以及检测装置的几何和电子特性，然而因果关系无法明确证明。除了与温度和外部露点有一些相似之处外，钴数据中的不稳定性更难与环境数据相关联。
