INTRODUCTION Drinking waters usually contain several natural radionuclides: tritium, radon, radium, uranium isotopes, etc. Their concentrations vary widely since they depend on the nature of the aquifer, namely, the prevailing lithology and whether there is air in it or not. AIMS In this work a broad overview of the radioactivity in drinking water is presented: national and international regu...

Historical Review The use of isotopes in clinical cardiology was introduced by Blumgart, Yens, and Weiss, who used radium C and a cloud chamber to estimate the linear velocity of blood flow in an extensive series of studies starting in 1927.1, 2 Undoubtedly the major stimulus to the adoption of tracer technics came from the introduction of man-made radioisotopes after World War II. During the i...

Radon is a gas with symbol Rn and atomic number 86. It’s an active, colorless, odorless, tasteless gas formed from decaying of uranium. It is one of the densest gas, and also a health hazard due to its radioactivity. Uranium is the parent compound from which radon is formed. Uranium has been there since the earth was formed. Thus it will be present for millions of years in the same concentratio...

Recently a new wave of interest to spectroscopy radioactive compounds has raised due successful applications the experimental ISOL/CRIS technique optical radium monofluoride molecules. This opens great prospects searches effects connected with ``new physics'' which point on deviations physical laws from those established by Standard Model elementary particles. Considerable advantages in experim...

BACKGROUND Radium-223 prolongs overall survival in patients with castration-resistant prostate cancer (CRPC) and symptomatic bone metastases, regardless of prior docetaxel. Whether or not chemotherapy can be safely administered following radium-223 treatment is of clinical importance. An exploratory analysis of prospectively collected data, from the ALSYMPCA (ALpharadin in SYMptomatic Prostate ...

This paper describes the Syrian experience with respect to Naturally Occurring Radioactive Materials (NORM) waste produced by the Syrian oil industry. Three main categories of NORM waste were identified. First, hard scales from decontamination of contaminated equipment and tubular that are considered to contain the highest levels of radium isotopes (Ra, Ra, Ra); this type of waste being current...
