The work is devoted to the study of the gamma background in the urban environment of Petropavlovsk-Kamchatsky (Kamchatka Territory), namely in parks and recreation areas. Measurements of the absorbed dose rate were carried out on a scintillation organic dosimeter developed by the team of the Tomsk Polytechnic University (TPU), which is a more budgetary analogue of the BDKG-01. In order to calculate the correction factor for converting the dosimeter readings from impulses/s to nSv/h, a number of calibration measurements were carried out with point sources of gamma radiation – 60Co and 137 Cs. The developed dosimeter carried out measurements with a duration of at least 5 minutes in various districts of the city of Petropavlovsk-Kamchatsky, special attention was paid to the study of technosphere objects made of materials that are natural sources of increased gamma radiation. Studies have shown that the monument to V. I. Lenin and the stele « City of Military Glory » in the center of the city of Petropavlovsk-Kamchatsky contain granites at their base, which give an overestimated gamma background.
Keywords: gamma background, dosimeter, spectrometry, average annual effective dose, monuments of Petropavlovsk-Kamchatsky.
