Comparative Measurements of WLS Fibers
The optical properties of several types of polystyrene WLS bers are compared. Fibers having diierent dopant and UV absorber concentrations, and with diierent claddings have been measured. Experimental results on the light yield, light transmission, and mechanical stress tolerance of these bers are presented. A comparative study of those properties is done for Kuraray, Bicron and Pol.Hi.Tech bers.
متن کاملDose-rate effects and dose and dose-rate effectiveness factor on frequencies of chromosome aberrations in splenic lymphocytes from mice continuously exposed to low-dose-rate gamma-radiation.
Dose-rate effects on chromosome aberrations in the low-dose-rate range have not been evaluated previously. The incidences of chromosome aberrations were analysed in splenic lymphocytes from female specific pathogen-free (SPF) C3H mice that were continuously irradiated with low- or medium-dose-rate (LDR, MDR) (137)Cs γ rays from 56 days of age to evaluate the dose-rate effects. The dose-response...
متن کاملGamma Dose Rate Measurement and Dose Rate Calculation for Sensitive Organs in the Vicinity of Hot Springs in Kerman Province
Introduction: All of the people worldwide are exposed to low levels of radiation. Cancer induction and genetic disorders are among the hazards of low level exposure. In some cases, radiation close to hot springs is higher than normal areas due to a high concentration and the decay products of Ra-226. Given the use of hot springs by the general public because of their therapeutic p...
متن کاملGenotoxic effects of high dose rate X‐ray and low dose rate gamma radiation in ApcMin/+ mice
Risk estimates for radiation-induced cancer in humans are based on epidemiological data largely drawn from the Japanese atomic bomb survivor studies, which received an acute high dose rate (HDR) ionising radiation. Limited knowledge exists about the effects of chronic low dose rate (LDR) exposure, particularly with respect to the application of the dose and dose rate effectiveness factor. As pa...
متن کاملRadiation Damage in Wls Fibres
Several types of WLS bres, candidates to be used in the TILECAL/ATLAS detector, were irradiated in a 60 Co source. Bicron, Kuraray and Pol.Hi.Tech bres were exposed to a total dose of 150 Krad. The degradation of light output was measured just after irradiation and followed during several days. The results are presented.
