Results of radon CR-39 detectors exposed in schools due two different long-term periods
Worldwide scientifi c studies have shown that indoor radon (Rn) is the main source of radiation exposure for the general population throughout the world [1]. Taking into account the health effects of Rn and its large-scale geographical and temporal variability, investigation of their concentrations in the living and working environments still affords scientifi c attention. Different methods to ...
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 کاملInvestigating Indoor Radon Concentration Using CR-39 Detector; a Case Study of Gachin Dwellings in Hormozgan
Introduction: Radon is a colorless inert gas which decay products are the main component of natural radioactive elements that are naturally produced in under layers of earth crust by decay of radium and uranium. It enters through buildings via gaps and cracks. Radon gas decay products like alpha particle can increase the incidence of lung cancer in human. Since every person sp...
متن کاملExperimental and Monte Carlo studies on the response of CR-39 detectors to Am-Be neutron spectrum
Background: The Poly-Allyl Diglycol Carbonate (PADC) detector is of particular interest for development of a fast neutron dosimeter. Fast neutrons interact with the constituents of the CR-39 detector and produce H, C and O recoils, as well as (n, α) reaction. These neutron- induced charged particles contribute towards the response of CR-39 detectors. Material and Methods: Electrochemical...
متن کاملCalculating CR-39 Response to Radon in Water Using Monte Carlo Simulation
Introduction CR-39 detectors are widely used for Radon and progeny measurement in the air. In this paper, using the Monte Carlo simulation, the possibility of using the CR-39 for direct measurement of Radon and progeny in water is investigated. Materials and Methods Assuming the random position and angle of alpha particle emitted by Radon and progeny, alpha energy and angular spectrum that arri...
