The radioactivity concentrations of natural radionuclides 232 Th, 40 K, 238 U, have been determined for various mushroom samples collected from black sea region in Ordu and Kastomonu provinces of Turkey. NaI (Tl) γ-scintillation counter is used for radioisotope concentration measurements. The radionuclide activity concentrations of 232 Th, 40 K, 238 U in the mushroom species were found to be ranging from 0.354 to 5.43, 4.37 to 90.9, 1.03 to 8.45 Bq/kg, respectively. Annual effective doses for ingestion of edible mushrooms were calculated and it is shown that exposure is mainly due to 232 Th natural radionuclides. The mean annual effective dose due to the intake of mushrooms was found to be 1.13 × 10-04 mSv.

“…The standards ISO 9696 and ISO 9697, both recently revised, are wellestablished methods for this. A standard based on the liquid scintillation counting (LSC) method, which requires reduced sample preparation and counting time (Forte et al, 2006), is in the final-draft stage (intended ISO 11704). This method is also applied in the active standard on measurement of tritium activity concentration (ISO 9698,under revision), and is intended for measurement of carbon-14 activity (ISO 13162, in preparation).…”

“…where C Rn-222 is the measured Rn-222 concentration, C 0,Rn-222 is the initial concentration at the sampling time and t is the time elapsed since collection (hours). During the radon-in-water analysis or if a water sample is taken and analyzed sometime later (rather than immediately), the sample's radon concentration will diminish, mainly due to radioactive decay and, partly, to the degassing phenomenon [30]. Then, it is essential to correct the resulting activity concentrations in order to take into account the decay from the sampling time to the analysis time.…”

In this paper, the evaluation of the Rn-222 radioactivity content in drinking water samples from the Calabria region, southern Italy, is reported as a case study. The Rn-222-specific activity in the analyzed groundwater samples for human use was evaluated by using the PerkinElmer Tricarb 4910 TR setup and compared with the parameter value (100 Bq L−1) reported in the reference Italian legislation, i.e., D.Lgs. 28/2016, derived from the European Directive 2013/51/Euratom. The radiological health risk for the population of the investigated area, due to the ingestion and inhalation of Rn-222 dissolved in water, was then evaluated by calculating the total annual effective dose, only in those cases where the parameter value was exceeded. The obtained results represent a main reference for the investigated area and are useful for determining any possible radiological health risk for human beings related to the ingestion of the investigated radionuclide. Moreover, they can also be used as a baseline for future investigations regarding background radioactivity levels.
