Determination of Radon, Uranium and Other Radioactive Isotopes’ Concentration in Different Types of Natural Water in Nenava Governorate

Abstract

Extended Abstract
Radon (²²²Rn) is a naturally occurring radioactive gas with a half-life of 3.82 days, released from the normal decay of the elements uranium, thorium and radium in rocks and soil. It is an invisible, colourless, odourless and chemically inert gas and has no taste. Radon is fairly soluble in water and organic solvents and seeps up through the ground and diffuses into the air. It dissolves into ground
water and surface water and can be released into the air when water is used. Radon is also present outdoors and indoors, but it is normally found at very low levels in outdoor air and in water from rivers and lakes.
