Results show that some locations lead to over-exposure, for example, external hazard indices H ex in some samples more than unity then it exceeds the upper limit of exposure. J Earth Sci Clim Change. Wendover Productions 2, views. Notes about measuring radiation: Sieverts are a measure of 'effective dose' - that means they measure the biological impact of the energy transferred to tissues from radiation. This was carried out by measuring Ra directly through the MITK12Videos 2, views. The outdoor absorbed gamma dose rate D out at 1 meter above the ground surface due to uniformly distributed natural radionuclides can be calculated as follows 2930 :.
