Background: Hair dyes are the important materials widely used by various peoples in Iraq and other countries. The present work investigates the presence of the effective radium content and radon exhalation rate in hair dyes samples. Materials and Methods: Twenty  hair dyes  samples were collected from Iraqi markets. Sealed can technique using LR-115 type II plastic track detector s ha...

There has been growing clinical evidence of the value targeted alpha therapy for treatment several cancers. The work slowed by lack availability key emitting isotopes, especially Ac-225. It can be produced photonuclear reaction, Ra-226(?,n)Ra-225. Ra-225 decays via beta-decay to Ac-225 with a half-life 14.9 days. This paper will provide technical description radium targets and target chamber th...

At the West Antarctic Peninsula (WAP), continued atmospheric and oceanic warming is causing significant physical biogeochemical changes to glaciers marine environment. We compare sediment sources drivers of macronutrient distributions at two bays along WAP during austral summer 2020, using radioactive radium stable oxygen isotopes trace sedimentary influences quantify different freshwater input...

We present high-resolution profiles of dissolved, labile, and total particulate trace metals (TMs) on the Northeast Greenland shelf from GEOTRACES cruise GN05 in August 2016. Combined with radium isotopes, stable oxygen noble gas measurements, elemental distributions suggest that TM dynamics were mainly regulated by mixing between North Atlantic-derived Intermediate Water, enriched labile TMs (...

The research aims to evaluate the radioactivity of samples foodstuffs Consumables in local markets thirteen items were selected which are rice, tea, drinking water, lentils, chickpeas, flour, red bean, crushed chickpeas and milk powder where concentrations specific activity chains uranium (238U), thorium (232Th) potassium (40K) measured using a gamma ray spectra analysis system with high purity...

Abstract Submarine groundwater discharge (SGD) has been widely recognized as an important source of dissolved nutrients in coastal waters and affects nutrient biogeochemistry. In contrast, little information is available on SGD impacts carbon budgets. Here, we assessed the associated (dissolved inorganic [DIC] total alkalinity [TA]) fluxes Liaodong Bay (the largest bay Bohai Sea, China) discuss...

THIS REVIEW is an attempt to answer two questions. First, are there any isotope technics available at the present time that are really useful in the care of patients? And second, what will be the role of isotope technics in clinical cardiology a few years from now? Historical Review The use of isotopes in clinical cardiology was introduced by Blumgart, Yens, and Weiss, who used radium C and a c...

St. Bartholmew's Hospital, and had the privilege of a visit to the Curie Fondation in Paris. I feel, therefore, that my views on the above subject may be of interest to the medical profession in India. The announcement of the discovery of radium was made at the Academie de Sciences in Paris on the 26th December, 1898?about 28 years ago?in a joint paper by M. and Mme. Curie. The first to discove...
