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 کاملAdsorption of para-hydrogen on krypton pre-plated graphite
Adsorption of para-hydrogen on the surface of graphite pre-plated with a single atomic layer of krypton, is studied theoretically by means of path integral ground state Monte Carlo simulations. We compute energetics and density profiles of para-hydrogen, and determine the structure of the adsorbed film for various coverages. Results show that there are two thermodynamically stable monolayer pha...

Diffusion processes invalidating the intra-arterial krypton-85 beta-particle clearance method for measurement of skin blood flow in man.
Krypton-85 dissolved in 0.9% NaCl was injected into the femoral artery of man; fi particles were measured over the skin of the eras. Cutaneous mean blood flow was calculated using the integral equation of Zierler based on the mean transit time analysis of clearance curves recorded from the cutaneous tissue; these calculations gave estimates which were only about one-fifth those obtained by othe...
متن کاملAdsorption Behavior of Cu(II) in Aqueous Solutions by SQD-85 Resin
The adsorption and desorption properties of SQD-85 resin for Cu(II) had been investigated. A series of experiments were conducted in a batch system to assess the effect of the system variables, i.e. initial pH, contact time and temperature. The results show that the optimal pH for the adsorption was 5.99 in the HAc-NaAc system, and the maximum adsorption capacity was estimated to 324 mg/g a...
