RESUMO
OBJECTIVE: Determine the radiation background in the Kropyvnytskyi microdistricts using the dosimeter-radiometer MKS-08-01 Gm «DKS-96¼ and a wireless sensor (dosimeter), analyze the measured values using the Student's t-test and create radiation background interactive map of Kropyvnytskyi microdistricts. MATERIALS AND METHODS: Measurement of Kropyvnytskyi radiation background was carried out in two ways: using the dosimeter-radiometer MKS-08-01 Gm «DKS-96¼ to measure the radiation background in the Kropyvnytskyi microdis- tricts (Zavadivka (sanitary zone and observation zone), Kovalivka, Velyka Balka, Lisoparkova, Raion 5/5, Popova, Miskyi sad); using a wireless sensor (dosimeter) with a monitoring system of the area radiation situation on the basis of Wi-Fi module with a microcontroller (Lisoparkova, Zavadivka (sanitary zone and observation zone), Raion 5/5). RESULTS AND CONCLUSIONS: Experiment results allowed us to conclude that in some microdistricts of Kropyvnytskyi increased level of radiation pollution. Evaluation of exposure for a human from technological reinforced naturally occurring radioactive sources, particularly from 238U and 222Rn is a key factor that determines the risk of cancerous pathologies in Kirovohrad region. We checked the effectiveness of our wireless sensor (dosimeter) for monitoring the radiation situation in the area. To analyze, interpret and report to the general public the results of our study, we created our own application for smartphones based on the Android operating system.
