Natural Sources of Ionizing Radiation
Many of our students seem to have well-defined but not necessarily well-founded opinions on the biological effects of ionizing radiation. During discussions of nuclear transformations in introductory chemistry and physics courses we might be able to help these students better understand the magnitude of these effects, and perhaps sort out the plethora of units with which radiation measurements ...
متن کاملPublic exposure to natural radiation sources (Ramsar Case Study)
Introduction: Human beings are naturally exposed to ionizing radiation in any environment. There are two main contributors to radiation exposures from natural sources: cosmic rays, Cosmo genic radionuclides, and radioactive nuclides that originated in the earth's crust. According to the latest data provided by the United Nations Scientific Committee on the Effects of Atomic Rad...
متن کاملEffective dose from natural background radiation in Keffi and Akwanga towns, central Nigeria
Background: Human is exposed to radiation in their environment with or without their consent and the exposure to natural background radiation is an unpreventable event on earth. Materials and Methods: An in situ assessment of the indoor and outdoor background radiation in Akwanga and Keffi towns of Nasarawa state Nigeria was carried out using a halogen-quenched Geiger Muller (GM) detector (Insp...
متن کاملNatural Gamma Radiation and Effective Annual Dose in Hot Springs in South Khorasan Province, Iran
Background and purpose: Background radiation exists naturally in the environment and human has been always exposed to it. These rays can affect living creatures and cause chromosomal damage, and genetic and somatic diseases. Hot water springs are a major source of background radiation. This study aimed at investigating the absorbed dose of environmental gamma and determining the annual effecti...
متن کاملPhysical characteristics and sources of exposure to artificial UV radiation
UV radiation belongs to the non-ionizing part of the electromagnetic spectrum and ranges between 100 nm and 400 nm; 100 nm has been chosen arbitrarily as the boundary between nonionizing and ionizing radiation. UV radiation is conventionally categorized into 3 regions: UVA (>315–400 nm), UVB (>280–315 nm) and UVC (>100–280 nm) (Figure 1). These categories have been confirmed by the Commission I...
