- Аннотация: 2)Results of a search for the masked regularities in the 214Po α-active isotope half- life solar-daily variation parameters in the data collected during 2012-2015 years arepresented. It is shown, that an amplitude of a sinusoidal function approximated half-life solar-daily dependence obtained by an averaging data at the 90 days for an each season of the years could reach ∼ 2.9·10−3 from the average daily value. Simila analysis of the 213Po data collected in the 2018-2022 years shows that amplitude of the deviation from the average value could reach ∼ 3.8·10−3. This effect limits an accuracy of the highly precision measurements with this or similar short-lived isotopes generating systematic errors if the data were collected at a relatively short time. The new value of the 213Po half-life which is τ(213Po) = (3.6984 ± 0.0006) µs was obtained on a base of the data collected at 2018-2022 years
