Discovery of the astatine, radon, francium, and radium isotopes
Currently, thirty-nine astatine, thirty-nine radon,??? isotopes have so far been observed; the discovery of these isotopes is discussed. For each isotope a brief summary of the first refereed publication, including the production and identification method, is presented. ∗Corresponding author. Email address: [email protected] (M.

متن کاملRadium and radon exhalation studies of soil
Background: Everyone is exposed to radon because it is present everywhere with varying concentrations. Radon and its progeny are well established as lung carcinogenic. Materials and Methods: Track etch technique using LR-115 plastic track detectors has been used to measure the effective radium content and radon exhalation rates in soil samples collected from urban area of Etah district...

متن کاملRadium isotopes in the Ulsan Bay.
In order to estimate the fluxes of Ra isotopes, we measured 224Ra, 226Ra, and 228Ra activities in the Ulsan Bay mixing zone. The convex upwards curvature of the plot of Ra isotope activities versus salinity for the mixing zone suggests that Ra isotopes are supplied from particles entering the mixing zone from both the river and bottom sediments. This addition increases the estuarine flux of 226...
متن کاملInception of standards for internal emitters, radon and radium.
THERE are three basic radiation protection standards which have their roots in observations on man. The detailed guidance for various situations of radiation exposure is derived in several ways from these three basic standards, or bench marks. The three basic standards are: (1) for external X-rays and y-rays, (2) for internal emitters, specifically radium, and (3) for inhaled radioactive aeroso...
