摘要

本文旨在通过测量放射性核素的活性浓度和氡的呼出率，估计塞尔维亚用于家庭供暖的不同种类煤的潜在辐射风险。得到的氡质量呼出率范围为(5.3 ?3.1) mBqkg 1 s ?1到70.3 ?9.4) mBqkg ?1，以褐煤型煤最高。据估计，储存在地下室的煤可以贡献高达50立方英尺/立方米的能量。3 .室内地面氡浓度。分析的煤样品中226Ra、232Th、40K、238U、235U和210Pb的活性浓度与以前报道的塞尔维亚使用的煤浓度一致。镭当量浓度和外部危害指数表明，废煤不存在显著的辐射危害。

Estimation of radiological impact on residents due to household storage of coal used for heating in Serbia

This paper aims to estimate a potential radiological risk from different kinds of coals used for domestic heating in Serbia, by measuring the activity concentration of radionuclides and radon exhalation rate. The obtained radon mass exhalation rate ranges from (5.3 ? 3.1) mBqkg?1s?1 to (70.3 ? 9.4) mBqkg ?1s?1 and was highest for lignite type of coal. It is estimated that coal stored in the basement could contribute up to 50 Bqm?3 of indoor radon concentration at the ground level. Activity concentrations of 226Ra, 232Th, 40K, 238U, 235U, and 210Pb in analysed coal samples agree with previously reported concentrations of coal used in Serbia. The values of radium equivalent concentration and external hazard index indicate that the used coal does not represent a significant radiation hazard.

期刊介绍： Nuclear Technology & Radiation Protection is an international scientific journal covering the wide range of disciplines involved in nuclear science and technology as well as in the field of radiation protection. The journal is open for scientific papers, short papers, review articles, and technical papers dealing with nuclear power, research reactors, accelerators, nuclear materials, waste management, radiation measurements, and environmental problems. However, basic reactor physics and design, particle and radiation transport theory, and development of numerical methods and codes will also be important aspects of the editorial policy.
