Use of LR-115 Detector to Measure Radon Concentrations in Milk and Tea Samples Collected From Misan Markets in Iraq
Introduction: Radioactive material is always present in the environment, and the largest contribution to the inhalation exposure comes from the short half-life decay products of radon. Accordingly, the concentrations of radon were measured in the milk and tea samples collected from Misanmarkets in Iraq. Material and Methods: A total of 2...
متن کاملEstimation of Radon Exhalation Rate and Radium Content in Soil Samples of Pathankot District, Punjab Using LR-115 Plastic Detector
In the present investigation, soil samples were collected from 10 villages belonging to Pathankot district, Punjab, India and assessed for radium content using LR-115 plastic detector. The ‘track etch’ technique has been employed for measuring the radium content. From the radium content, radon exhalation rates and mass exhalation rates were calculated for these samples. The mass exhalation rate...
متن کاملSurface 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...
متن کاملLong-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 کاملPassive monitoring of the equilibrium factor inside a radon exposure chamber using bare LR 115 SSNTDs
In this paper, we propose and study a method using bare LR 115 SSNTDs for passive monitoring of the equilibrium factor F inside a radon exposure chamber. The method is based on the proxy equilibrium factor Fp which is defined as Fp 1⁄4 r=ðriC0tÞ 1, where ri is the partial sensitivity (i.e., the number of tracks per unit area per unit exposure), C0 is the radon gas concentration and t is the exp...
