Elements of Natural Radioactive Decay Series in Iranian Drinking Water and Cigarettes
2010
Arhiv za Higijenu Rada i Toksikologiju
The uranium ( 238 U) decay series provides the most important isotopes of elements radium ( 226 Ra), radon ( 222 Rn), and polonium ( 210 Po) with half-lives of about 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. In this study, we used the average concentrations of naturally occurring radionuclide 226 Ra
