Abstract:
This study aimed to minimize radiation risk in Solok Selatan by analyzing active concentrations of 226Ra, 232Th, and 40K, calculating excess lifetime cancer risk (ELCR) from annual effective dose equivalent (AEDE). Soil samples from seven sites in the Solok Selatan, 0 – 5 cm deep, were tested with a high-purity germanium (HPGe) detector. 232Th concentrations exceeded the established global standard of 30 Bq/kg. In addition, the study included the determination of Radium Equivalent (Raeq), absorbed gamma dose rate (D), AEDE, and ELCR. Annual effective dose ranged from 68.33 to 19.92 μSv/y, belo

Abstract Introduction The compensation criteria for lung cancer in Asbestos Damage Relief Act (ADRA) in Korea mainly rely on the presence of radiologic findings of asbestosis or pleural plaque. Although exposure criteria with asbestos fiber concentration in lung tissue is supplementary, it has not been applied. Because only 30% of asbestos related lung cancer has asbestosis or pleural plaque, substantial lung cancers might not be compensated by ADRA. Exposure criteria for lung cancer need to be applied in ADRA. Methods Data of 1,784 lung cancer compensation applicants during 2011-2021 were ana

Abstract Natural radiation is a feature of the environment in which we live. One of the contributions of human exposure to ionizing radiation due to natural sources arises from gamma radiation. Therefore, present study was aimed to evaluate and map indoor gamma dose rate in Tehran. The corresponding annual effective dose (AED) and excess lifetime cancer risk (ELCR) were also calculated. All measurements were performed by a Geiger Muller detector in 43 dwellings in Tehran. The average indoor gamma dose rate in Tehran was appointed as 343.2 nGy/h. AED and ELCR were calculated as 2.4 mSv and 10.3

This study assessed the levels of gamma radiation exposure and associated excess lifetime cancer risk (ELCR) in Bompai area, Kano State, Nigeria. Gamma dose rate measurements were taken at 500 points across residential, educational, healthcare, industrial, and commercial sites using Radiation Alert Inspector. The results showed a mean gamma dose level of 17.794×10–3 μSv/hr, corresponding to an annual effective dose (AED) of 380.2×10–6 mSv/yr and an ELCR of 1500×10–6.

Abstract:
Purpose: A study was conducted to estimate the Annual Effective Dose Equivalent (AEDE) and Excess Lifetime Cancer Risk (ELCR) caused by the presence of an artificial cobalt-60 radioactive source producing ionizing radiation levels within the radiotherapy facility at Komfo Anokye Teaching Hospital (KATH) in Ghana. This study validated the safety of cobalt-60 radioactive sources, as well as the notion of calculating the Annual Effective Dose Equivalent (AEDE) and Excess Lifetime Cancer Risk (ELCR), which contributed to reducing occupational and public exposures inside the facility.

Abstract:
To assess the health impacts of radon exposure over a lifetime, in the present study, the annual effective dose (AED) and cumulative excess lifetime cancer risk (ELCR-C) were evaluated by considering various indoor microenvironmental exposures based on age-specific time–activity patterns using Monte Carlo simulations. Significant regional variations in indoor radon concentrations across the Republic of Korea were observed, with the highest levels found in schools and single detached houses. Based on the standard annual total of 8760 h spent indoors and outdoors, the AED varied by age group and

The inadvertent ingestion of contaminated soil is the dominant exposure route of non-volatile and semi-volatile contaminants such as polycyclic aromatic hydrocarbons (PAHs). Quantitative mass balance soil ingestion studies have been used to determine soil ingestion rates for use in human health risk assessments (HHRA) that can be used to predict the likelihood of adverse effects in individuals exposed to hazardous contaminants such as PAHs in contaminated soil. The Cold Lake region of Alberta is one of the three major oil sands regions of Alberta, and PAH concentrations in this oil sand region
