Keywords- Concentration, Gamma Exposure, Hazard Indices, Natural Radionuclides, Soil Sediments I. Introduction 1. Introduction Radionuclides are found in natural surroundings, mostly in the air, soil and water. Radionuclide means type of atom that exhibits radioactivity. Each radionuclide is characterized by its own half-life, which is the time.

EPA, Washington, DC (). Exposure to Radionuclides (FRG # 13), September This document is a compilation of risk factors for doses from external gamma radiation and internal intakes of radionuclides. FRG #13 is the basis of the radionuclide risk coefficients used in the EPA Health Effects Assessment Summary Tables (HEAST, EPA ) and in computer dose codes such.
The brine water flowed across a livestock field, entering a stream and then a city reservoir, forcing the town to temporarily shut it down. (The EPA safe drinking-water. SourcesThere are two sources of radioactive contamination in drinking water. The first is naturally occurring radionuclides contained in the soil that water moves through.
Some areas in Florida are susceptible to contamination from phosphate-rich soils and rock. The second source of radioactive contamination comes from man-made sources. There is no known man-made contamination. As part of a broader effort to calculate effective dose rate coefficients for external exposure to photons and electrons emitted by radionuclides distributed in air, soil or water, age-specific stylized phantoms have been employed to determine dose coefficients relating dose rate to organs and tissues in the body.

How the EPA conducts risk assessment to protect human health and the environment. Several assessments are included with the guidelines, models, databases, state-based RSL Tables, local contacts and framework documents used to perform these assessments.
As part of a broader effort to calculate effective dose rate coefficients for external exposure to photons and electrons emitted by radionuclides distributed in air, soil or water, age-specific. impact, called a dose, can be caused by radionuclides released to air and/or water, or radiation emanating directly from buildings or other objects at PORTS.
U.S. EPA sets a 10 mrem/year limit for the dose from radionuclides released to the air, and DOE sets a mrem/year limit for the dose from radionuclides from all potential pathways. Regulations for controlling exposure of the public to radionuclides are often dose-based.
Because the doses result from interaction of humans with radionuclides contained in environmental media—air, water, soil, and biota—a knowledge of the behavior of naturally occurring radionuclides in these media is needed (Landa ).
For external doses, the report is called “External Exposure to Radionuclides in Air, Water, and Soil”. The factors found in these two reports are useful for assessing the radiation dose to individuals who can be reasonably characterized as equivalent to “Reference Man”.
Federal Guidance Report No. 12 tabulates dose coefficients for external exposure to photons and electrons emitted by radionuclides distributed in air, water, and soil.
The dose coefficients are intended for use by Federal Agencies in calculating the dose equivalent to organs and tissues of the by: Terrestrial radiation comes from many naturally occurred radioactive elements, for example Radon, in the water and air.
Food that contains isotopes such as C and K could lead to small radiation doses. In addition, plants and animals that uptake radioactive elements from soil or food could accumulate radioactive materials.
