The study compared the daily mean intensity of one-minute-step fluctuations in intensity of the secondary cosmic rays reflected by neutron count rate and dynamics of body temperature, motor activity, as well as concentration of glucocorticoid hormones in birds and rodents. A positive correlation was established between body temperature oscillations and neutron count rate fluctuations. A similar correlation was observed between physical parameter (neutron count rate), on the one hand, and daily mean motor activity and concentration of glucocorticoid hormones in the animals. The periods and phases of these processes presented in synchronous time series coincided. The facts of simultaneous variations or disturbances of the periods in dynamics of biological and physical parameters attest to their relationships. The study concluded that the infradian rhythms with the periods of 3-5 days depend on some external environmental factor related to fluctuations in intensity of secondary cosmic rays.
该研究比较了鸟类和啮齿动物的一分钟步长强度的日均值波动强度、体温、运动活动以及糖皮质激素浓度的中子计数率和动力学的关系。体温波动与中子计数率波动之间存在正相关。在动物中，物理参数（中子计数率）与每日平均运动活动和糖皮质激素浓度之间也观察到类似的相关性。这些过程的周期和相位在同步时间序列中重合。生物和物理参数动力学中周期的同时变化或干扰的事实证明了它们之间的关系。该研究得出结论，周期为 3-5 天的亚日节律依赖于与次级宇宙射线强度波动有关的某些外部环境因素。
