Depending on the grade and characteristics of the uranium deposit, the radiological hazard considerations may widely vary. Although short lived radon progeny are the major contributor of individual dose to the miners, dose assessment using their activity concentration data is normally avoided. Mine dust, diesel fumes, high humidity and seepage from the surrounding surface poses additional difficulty in direct estimation of radon progeny activity concentration. Individual doses are computed through radon (222Rn) monitoring data and equilibrium ratio (F) between radon and its short lived progeny. Both ambient and passive techniques are used in Indian uranium mines for the dose assessment but the passive technique is preferred over the ambient as the later can explicitly account the individual worker during its uses.

The Earth’s atmosphere contains approximately 0.087 ppm of stable xenon. Radio xenon isotopes like 133Xe and 135Xe are artificial isotopes generated from various nuclear facilities. Atmospheric measurement of radioactive xenon isotopes (radio xenon) plays a key role in remote monitoring of any nuclear accidents, abnormal release from nuclear facilities or nuclear explosions, since radio xenon has a high capability to migrate in a wide range from the site. The measurement of these gamma-emitting radioxenon gas can be done by sampling the gas in measurement geometry (like gas cell) and counting the cell in suitable gamma spectrometry-based detector system. For measurement of radioactive content in the sample, the efficiency calibration of system has to be carried out with same measurement geometry and same gamma ray energy that of sample. Many times, the radioactive standard sources in same measurement geometries and for same gamma energies are not feasible. In such cases, experimentally validated computational techniques are used for generating efficiency function. This paper describes the application of computational technique for measurement of radio xenon (133Xe and 135Xe) gas in the environment.</div>","PeriodicalId":689,"journal":{"name":"MAPAN","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139096571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
