background: radium-226 (226ra) is a product of the 238u radionuclide decay series that significantly incorporated into the human body through water intake. it can also potentially cause a series of health problems including cancers of the digestive system. radium-226 (226ra) is a product of the 238u radionuclide decay series that significantly incorporated into the human body through water inta...

abstract background: and soils with which it comes in contact. there is dual exposure from radon in water i.e. due toinhalation of the radon released from the water into the ambient air and through ingestion whenwater is used for drinking. as radon contaminated water adversely affects the health, it istherefore fundamental from health and hygiene point of view to measure radium concentrationand...

ABSTRACT  Background: The essential constituents of cements like lime, silica and alumina are derived from earth’s crust in which radioactive elements like uranium, thorium etc are also present in varying amounts almost everywhere. These two elements are considered as the parent elements of uranium and thorium radioactive decay series in which radon and thoron are produced respectively as decay...

The Uranium (U) decay series provides the most important isotopes of elements Radium (Ra), Radon (Rn) and Polonium (Po) with half-lives of 1600 years, 3.8 days and 140 days, respectively. Although the chemical structure of radium is very similar to calcium, the fact that it produces a radioactive gas (Radon) complicates its handling in the laboratory and natural environment. The average concent...

BACKGROUND The economic value of unconventional natural gas resources has stimulated rapid globalization of horizontal drilling and hydraulic fracturing. However, natural radioactivity found in the large volumes of "produced fluids" generated by these technologies is emerging as an international environmental health concern. Current assessments of the radioactivity concentration in liquid waste...

The measurements of Ra, Th and K using gamma spectrometry and radon concentration and exhalation rates measurements using solid state nuclear track (LR-115, Type-II plastic) detectors are used to asses a first order exposure risk for the persons residing in Fatehbad and Hissar districts of Western Haryana, India. The concentration of Radium, Thorium and Potassium in the soil samples varies from...

Radon and radium could pose serious risk to human health that is why our preliminary research was concentrated on their concentration in tap drinking waters from the Kavadarci municipality. We sampled three locations within city limits there have been determined radon concentrations respectively. of 0.53 Bq/l; 0.70 Bq/l 0,87 were for samples K1, K2 K3, respectively, which are 12 21 times less t...
