Analysis of krypton-85 and krypton-81 in a few liters of air.
Long-lived radioactive krypton isotopes, (81)Kr (t1/2 = 229,000 year) and (85)Kr (t1/2 = 10.76 year), are ideal tracers. (81)Kr is cosmogenic and can be used for dating groundwater beyond the (14)C age. (85)Kr is a fission product and can be applied in atmospheric studies, nuclear safety inspections, and dating young groundwater. It has long been a challenge to analyze radio-krypton in small sa...
متن کاملMeasurement of intrarenal anatomic distribution of krypton-85 in endotoxic shock in dogs.
Renal blood flow distribution was measured in control dogs and dogs in endotoxic shock by utilizing a modification of 85Kr washout. Kidneys, injected with 85Kr via a renal arterial cannula, were removed at several specific intervals after injection, rapidly frozen, and sectioned transversely so that pieces of tissue could be isolated and counted for radioactivity. Control outer cortical blood f...
متن کاملUse of Krypton-85 in the Study of Hypoxia in Porto-pulmonary Bilharziasis (schistosomiasis).
BRITS 1021 observations it was found that the immediate effect of the adrenergic drugs was similar. To obtain a measure of the duration of effect of the different inhalants, serial assessments were continued for three and a half hours after each inhalant therapy on two groups of asthmatic subjects containing 12 subjects in each group. From these serial studies it was found that the inhalants ga...
متن کاملDosimetry of blood irradiation with radiochromic film.
It has been shown that radiochromic film is an ideal dosimeter for assessment and verification of delivered dose to irradiated blood products. Using a parallel opposing two-field technique on a medical linear accelerator, blood is irradiated to diminish the risk of transfusion-associated graft vs. host disease (TA-GVHD). The blood products are irradiated in a Perspex blood box to an applied dos...
متن کاملKrypton-85 in the Detection of Intracardiac Left-to-right Shunts.
ANUMBER of methods have been developed for detecting left-to-right shunts during cardiac catheterization of which the most frequently employed is determining the difference in oxygen saturations. This method has limited application in the presence of small shunts, however, since the minimal changes are often within the error of this method.' Therefore, other more sensitive technics have been em...
