“…This statistic represents the yearly dosage equivalent received by the reproductive organs of the population (gonads). The activities of bone marrow and bone surface cells are also included as organs of interest in this context (Attallah et al, 2020).…”

Following up with radiological parameter analysis, gamma spectrometry was used to assess the specific activity of 238U, 232Th, and 40K in sediment samples collected at Gosong Beach, on the west coast of Kalimantan Island, Indonesia. Except for 40K, the mean activity levels of 238U, 232Th, and 40K were within the range of the global average. However, the radiological effects of radionuclides at Gosong Beach were found to be safe and no health hazards for the population of Gosong Beach, except for the annual gonadal dose equivalence, which was found to be slightly higher than the global average.

“…Long time exposure to nuclear particles emissions from building materials may lead to several health issues [9]. The type of building material and where it is sourced from can determine the amount of radionuclides in the material since building materials reflect their geologic formation and origin [10,11]. Background radiation is a measure of the ionizing radiation present in the environment at a particular location which is not due to deliberate introduction of radiation sources.…”
The gamma dose rate exposure levels from different brands of building materials at commercial distribution stores/shops in two major cities in Ondo State, Nigeria, were measured using a well calibrated Inspector 1000 scintillator detector. The results showed that the different brands of building materials which are Corrugated iron sheet, Aluminum roofing sheets, Conduit pipes, Paints, Cement, PVC pipes, Wash hand basin, Bath tub, Water closet, Kitchen zinc, Asbestos, Floor tiles, Wall tiles, Bullet proof door, Binding wire, rings and rods, Red bricks, Galvanized pipes, Copper pipes, Water tanks contributed excess annual effective doses of 0.332 mSv/y and 0.311mSv/y to store keepers in Ikare Akoko and Akure cities respectively. The indoor and outdoor annual effective dose of each of the investigated two cities are correlated using simple linear regression equations. The results of the modeling and experiment show that annual effective dose received by the occupants of these shops/stores was about 12 % higher than what could be received in a typical natural radiation environment in the two cities because the building materials acts as a source of radiation indoor. The research indicated that the typical habit of using poorly ventilated and confined space as stores/shops by the sales men might subject them to internal exposure through inhalation of radon gas and its short-lived decay products. Implementation of the developed equations would definitely promote rapid determination of outdoor annual effective dose through indoor annual effective dose and ultimately save time and other valuable resources.
“…Based on the secondary data from Nuclear Energy Regulatory Agency of Indonesia (BAPETEN), the amount of tin slag that contains TENORM from tin industry in Bangka Island is approximately 43,800,000 kg (Iskandar et al, 2019). From the results of field observations, it was found that many people, including workers, store tailings and slag in their homes where the tailing and slag materials have potential radiological impacts on workers and residents, which can pose radiation exposure to them and contaminate the environment (Attallah et al, 2020).…”
This study assessed the potential radiological impact of a class 3 landfill as a disposal facility of the final tin slag from the tin industry in Bangka Island. Tin slag that contains TENORM (Technically Enhanced Naturally Occurring Radioactive Material) with activity concentrations above exemption level limits should be stored safely and securely. The radiological impact analysis of storing TENORM waste was carried out before and after the construction of a landfill facility. RESRAD OFFSITE version 3.2 software was used to simulate dose and cancer risk, and analyze the contribution of exposure pathways. Radionuclide concentration, landfill facility specifications, hydrogeological data, climatological data, and food and water consumption data were used as input parameters of RESRAD. The receptor was a resident farmer who lives 100 meters from the facility, grows his own food, and consumes water from his land. The total dose before and after the construction of the landfill were 3.13 mSv/year and 1.84×10-2 mSv/year while cancer risks were 5.69×10-3 and 6.50×10-5, respectively. The exposure pathways from inhalation of radon become a major contributor to dose acceptance and cancer risk. Based on these results, the landfill facility is effective in reducing the potential impact of radiological hazards from dose acceptance and cancer risk.
