This paper includes the results of measurements of natural radioactivity in building materials and raw building materials. The dose rate indoors was calculated on the basis of the contents of K-40, Ra-226 and Th-232 in building materials and the results were compared with literature data of measurements (in situ). The standard procedure for qualifying building materials for building houses designed for habitation was used.

This paper presents the results of measurements of natural radioactivity of K-40, Ra-226 and Th-232 in building material as well as radon concentrations and dose rates in houses and outdoors. The mean absorbed rate in air outdoors from natural gamma radiation was found to be 40.2 nGyh'1. Doses inside houses made from particular materials were (nGyh '): brick - 102, prefabricate - 89, wood - 88. The mean equivalent concentration of radon indoors was 12 Bqm-3. The calculated annual effective dose equivalent per one statistical inhabitant of "Poland Green Lungs" is 1.61 mSv/year. The doses absorbed by the population in the northeastern region of Poland from natural sources of ionizing radiation are lower than the population-weighted world averages.

The article presents the results of studies on the content of artificial (¹³⁷Cs, ⁹⁰Sr) and natural radionuclides (²²⁶Ra, ²³²Th, ⁴⁰K) in tissues and organs of various individuals of pumpkinseed Lepomis gibbosus (Linnaeus, 1758) from the Zaporizhzhia (Dnipro) reservoir. It has been revealed that in the bones of sexually mature pumpkinseed females, the content of radionuclides ¹³⁷Cs and⁹⁰Sr is 24.7% and 28.6% less, respectively, than in the bones of males. Summing up the materials of radioecological studies of 2017–2018, the following sequence of tissues and organs of the pumpkinseed by the ability to accumulate radionuclides was obtained: bone> muscle> scales> gills. Research results can be useful for further study on the fish radiation load in the basins of the Dnipro River and during monitoring radioecological research. It was determined that the content of radionuclides in the pumpkinseed muscles did not exceed the permissible levels of radionuclide content for fish as a food product (permissible levels of radionuclide content for ¹³⁷Cs – 150 Bq/kg, ⁹⁰Sr – 35 Bq/kg).
