Long-term determination of airborne radon progeny concentrations using LR 115 solid-state nuclear track detectors
This paper described the establishment of lognormal distributions for the Jacobi room model parameters with a view to improve an existing method for long-term passive measurements of the equilibrium factor using LR 115 solid-state nuclear track detectors, namely, through the proxy equilibrium factor (Fp) method. Fp is defined as (C1 þ C3)/C0 where C0, C1 and C3 are the concentrations of 222Rn, ...
متن کاملUranium concentration in blood samples of Southern Iraqi leukemia patients using CR-39 track detector
The simple and effective technique of fission track etch has been applied to determine trace concentration of uranium in human blood samples taken from two groups of male and female participants: leukemia patients and healthy subjects group. The blood samples of leukemia patients and healthy subjects were collected from three key southern governorates namely, Basrah, Muthanna and Dhi-Qar. These...
متن کاملA further study of the (CR–LR) difference technique for retrospective radon exposure assessment
The (CR–LR) difference technique, based on the CR-39 and LR 115 detectors, for the determination of implanted Po in glass after deposition of short-lived radon progeny, was analyzed in details in this paper. The sensitivities of both detectors were calculated using the Monte Carlo method with V functions particularly derived in our previous works for the detectors used in the present experiment...
متن کاملAlpha-particle radiobiological experiments using thin CR-39 detectors.
The present paper studied the feasibility of applying comet assay to evaluate the DNA damage in individual HeLa cervix cancer cells after alpha-particle irradiation. We prepared thin CR-39 detectors (<20 microm) as cell-culture substrates, with UV irradiation to shorten the track formation time. After irradiation of the HeLa cells by alpha particles, the tracks on the underside of the CR-39 det...
متن کاملLong-term determination of airborne radon progeny concentrations using LR 115 detectors and the effects of thoron.
The 'proxy equilibrium factor' (F(p)) method has been developed for long-term determination of airborne radon progeny concentrations using LR 115 solid-state nuclear track detectors. In this paper, the effects of (220)Rn on the F(p) method have been studied. The correction to the track density was related to a parameter α which was the ratio of the sum of activity concentrations of alpha-partic...
