BACKGROUND Automated protocols for measuring and dispensing solutions containing radioisotopes are essential not only for providing a safe environment for radiation workers but also to ensure accuracy of dispensed radioactivity and an efficient workflow. For this purpose, we have designed ARAS, an automated radioactivity aliquoting system for dispensing solutions containing positron-emitting ra...

background: some particular areas contain natural radionuclide at levels much higher than those usually present in earth's crust. the radiological impact of the use of zirconium ore in zirconium industry is due to internal exposure of the lung by alpha particles and external exposure of the body by the gamma rays. the result of gamma spectrometry measurement of the concentrations of the na...

This mass balance study investigated the metabolism and excretion of eribulin, a nontaxane microtubule dynamics inhibitor with a novel mechanism of action, in patients with advanced solid tumors. A single approximately 2 mg (approximately 80 μCi) dose of [¹⁴C]eribulin acetate was administered as a 2 to 5 min bolus injection to six patients on day 1. Blood, urine, and fecal samples were collecte...

Introduction: This study covered the assessment of the natural radioactivity levels and heavy metalsconcentration in dust samples collected from selected schools in the holy Governorate of Karbala. The purpose of thisstudy was to assess the radiological health and safety impact of dust pollution on the children going to school. Material and Methods:</...

1. Spermatozoa collected directly from the testis of the conscious ram contain 25% more phospholipid than ejaculated spermatozoa. The concentration of lecithin, phosphatidylethanolamine and ethanolamine plasmalogen was greater in testicular spermatozoa; little difference was observed in choline plasmalogen. Both types of spermatozoa had significant amounts of cardiolipin and alkyl ether phospho...

1. Studies have been made of the time-sequence of protein metabolic and hormonal changes following an abrupt increase in carbohydrate or fat intake. [3H]leucine and [14C]urea were infused for 72 h, via the aorta, into fourteen female pigs (30-38 kg body-weight). At 24 h after the start of the infusion their feed was either changed to one of two isonitrogenous diets containing additional starch ...

With the improvement of people's requirements for living environment, effect indoor radon radioactivity on health has been widely concerned. In this paper, taking a university in Shanghai as an example, concentration and its related environmental parameters were measured some houses to understand level campus. The results show that average concentrations student dormitory, office building, acad...

The Jiangmen Underground Neutrino Observatory will build the world's largest liquid scintillator detector to study neutrinos from various sources. 20 kt be stored in a $\sim$600 t acrylic sphere with 35.4 m diameter due good light transparency, chemical compatibility and low radioactivity of acrylic. concentration U/Th is required less than 1 ppt (10$^{-12}$ g/g) achieve radioactive background ...
