Determining the probability of locating peaks using computerized peak-location methods in gamma-ray spectra as a function of the relative peak-area uncertainty

Negative correlation between the number of sunspots and the occurrence of 7Be and 22Na in the surface air and their contribution to radiation doses

“…Long-term measurements, performed in the framework of an environmental radioactivity monitoring programme designed for assessing doses to the general population due to natural radioactivity and emissions of radioactive substances from the nuclear power plant Krško are sensitive enough to establish activity concentrations of cosmogenic radionuclides 7 Be and 22 Na in the atmosphere over many years. However, the sensitivity of spectrum analysis should be improved in order to determine 22 Na activity in the air during the cold season more reliably (24). The measured activities in aerosols (surface air) indicate that 7 Be and 22 Na follow the same pathways from the stratosphere to the surface air and that the production of 22 Na is more sensitive to the solar activity than the production of 7 Be.…”
