“…We believe that artificial tritium emissions due to either weapon tests or nuclear facilities do not account for the pattern which we have shown to be synchronous with the solar cycle. Our previous study has demonstrated that an emission of 3.5 × 10 12 Bq year −1 (1.8 × 10 21 tritium atoms year −1 ) cannot be observed in precipitation farther than 5 km apart the source 38 .…”

The relationship between the atmospheric concentration of cosmogenic isotopes, the change of solar activity and hence secondary neutron flux has already been proven. The temporal atmospheric variation of the most studied cosmogenic isotopes shows a significant anti-correlation with solar cycles. However, since artificial tritium input to the atmosphere due to nuclear-weapon tests masked the expected variations of tritium production rate by three orders of magnitude, the natural variation of tritium in meteoric precipitation has not previously been detected. For the first time, we provide clear evidence of the positive correlation between the tritium concentration of meteoric precipitation and neutron flux modulated by solar magnetic activity. We found trends in tritium time series for numerous locations worldwide which are similar to the variation of secondary neutron flux and sun spot numbers. This variability appears to have similar periodicities to that of solar cycle. Frequency analysis, cross correlation analysis, continuous and cross wavelet analysis provide mathematical evidence that the correlation between solar cycle and meteoric tritium does exist. Our results demonstrate that the response of tritium variation in precipitation to the solar cycle can be used to help us understand its role in the water cycle.

This study was focused on the 3 H activity levels in the unique ''tritium valley'' around the Mohelno reservoir, which receives outlet cooling waters from the Dukovany nuclear power plant. Tritium activity levels above the background reference value were found in water from the reservoir and from the effluent part of the Jihlava water, in air moisture and in plant tissues tissue free water tritium (TFWT), and nonexchangeable organically bound tritium (NE-OBT). These zones were discernible that had noticeably different TFWT and NE-OBT values: (1) littoral zones, (2) slopes above the reservoir, (3) plateaus above the reservoir/river.Keywords Mohelno reservoir Á Dukovany nuclear power plant Á Tissue free water tritium Á Non-exchangeable organically bound tritium
