We evaluate lifetime attributable risks induced by increasing concentration of cosmic radiation and cosmogenic
radionuclides during periods of low solar activity for the specific conditions in the Czech Republic. The concentration
of cosmic radiation and cosmogenic radionuclides reaches the highest values during the solar minima when
their penetrability into the Earth magnetosphere is enforced. The computed estimate of lifetime attributable risks
from solid neoplasms (colon, lung, and stomach) induced by natural background dose is higher for the period of
the low activity solar cycle No. 24 than for the previous period of forced solar activity of the solar cycles No.
19 – No. 23. We estimated lifetime attributable risks induced by annual natural background dose by sex for the
Czech Republic and USA. In addition, three different scenarios based on dose radiation level were explored. The
cosmogenic radionuclides in our environment may thus play a greater role than in the last decades.
