Estimation of Indoor 222Rn Concentration in Lima, Peru Using LR-115 Nuclear Track Detectors Exposed in Different Modes

نویسندگان

چکیده

Radon is the main source of natural radioactivity, and its measurement considered extremely important in radioprotection, given relationship with occurrence lung cancer. In last two years, measurements this radioactive gas were carried out Lima considering a grid 5 km2 population density to determine number be out. Cellulose nitrate nuclear track detectors exposed bare mode diffusion chamber used estimate 222Rn concentrations. mode, non-commercial monitors commercial used. The monitoring results are presented for 43 districts Province whose approximately ten million inhabitants occupying total area 2655.15 km2. Measurements made obtaining an average concentration 49 Bq·m−3 using 66 chambers. Average concentrations obtained by both detector exposure modes below maximum recommended WHO. A radon (222Rn) map was also as visual representation levels province inverse distance weighting (IDW) interpolation.

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, ...

Measurements of Indoor Radon Levels in India using Solid~State Nuclear Track Detectors: Need for Standardisation

Solid-state nuclear track detectors are being used to obtain the time integrated concentration levels of indoor radon/thoron and their daughters. This technique is preferred for taking such measurements in dwellings Such measurements are important as the radiation dose to human beings due to indoor radon constitutes more than 50 per cent of the total dose including that received from the natura...

Surface Chemical Etching Behavior of Lr-115 Type Ii Solid State Nuclear Track Detector

Solid State Nuclear Track Detectors (SSNTDs) are well known for the detection of ionizing radiation through track formation of heavy ionizing particles. The LR-115 detector is a commonly used SSNTD for the detection and measurement of Rn and its progeny. Several techniques of track revelation are known but, the chemical etching technique is the most frequently used in which tracks can be made v...

Nuclear Track Detectors

Approximately half of the human exposure to radiation is due to indoor airborne shortlived progeny (decay products) of the radon gas (Rn). To measure the airborne concentrations of radon gas and/or its progeny, Nuclear Track Detectors (NTDs) are usually employed. The NTDs register the alpha particles emitted by radon gas and its progeny in the form of tracks in the NTDs, which will become visib...

Theoretical basis for long-term measurements of equilibrium factors using LR 115 detectors.

In this paper, we propose a method to determine the equilibrium factor using a bare LR 115 detector. The partial sensitivities rhoi of the LR 115 detector to 222Rn and its alpha-emitting short-lived progeny, 218Po and 214Po, were investigated. We first determined the distributions of lengths of major and minor axes of the perforated alpha tracks in the LR 115 detector produced by 222Rn, 218Po a...
