本课程“如何撰写科学研究论文（WMD CBRN）1”旨在探讨电离辐射的影响及其在现代社会中的重要性。课程从人类早期对辐射影响的认识不足讲起，追溯了辐射防护概念的提出和演变，介绍了国际上关于职业人员和普通民众的安全剂量标准（如每年5毫希沃和1毫希沃）。 课程强调了近年来在全球范围内进行的室内空气氡气测量以及在美国环境保护署（EPA）等机构进行的广泛研究，揭示了相当比例的建筑物中氡气含量超标的普遍现象。此外，课程还提及了各国对辐射背景和建筑物内辐射剂量率的持续监测，以及北约军队如何建立环境危害军事设施数据库。 这些研究的必要性在于，科学已证实电离辐射即使在低剂量、长期暴露下也对人体具有有害的生物学效应。课程将21世纪的环境放射性污染问题称为“原子时代”的挑战，并指出尽管核能发展曾被视为不可替代的路径，但如今人们已认识到其危险性，并转向开发替代能源。 因此，本课程的核心在于强调研究部队驻地（包括营房及周边地区）的辐射背景，评估部队人员的有效剂量的辐射暴露，研究其发病率，并据此规划和实施相应的健康改善措施。这突显了理解和管理辐射暴露对于部队健康和安全至关重要。
Although humans were constantly exposed to cosmic rays, radon, and radionuclides in the Earth's crust, the effects of ionizing radiation were poorly understood until man invented artificial sources of radiation The first idea of limiting radiation exposure was expressed by the English scientist W. Rollins in 1902. According to his proposal, a safe dose was taken as a dose corresponding to an exposure dose of 10 R/day. Further recommendations were made by individual authors and international committees that discussed these issues at scientific conferences and symposia of various levels , and today 5 mSv/year is permissible for professionals, and 1 mSv/year for the populationIn most developed countries, measurements of radon activity in indoor air have been widely carried out in recent years The US Environmental Protection Agency, after measuring radon levels in more than 2 million homes, schools, and workplaces, found that 30% of buildings in one state had radon levels above the norm.Many countries around the world and in Europe also measure the radiation background and exposure dose rate in areas and buildings.Most NATO forces have a computer database of all environmentally hazardous military facilities. Such intensive research is warranted by the fact that science has confirmed the harmful biological effects of ionizing radiation not only at high doses, but also at low doses over a long period of time The 21th century, the period of global radioactive pollution of the environment, called the "atomic century", has passed in such a way that it has raised the question of the future existence or non-existence of nuclear energy. Humanity has clearly presented the danger of radioactive pollution and is making every effort to eliminate it. If by the beginning of the 70s the development of nuclear power was perceived as the main (only and unalternative) path of humanity, today all attention has been transferred to alternative energyFrom all of the above, it is clear how important it is to study the radiation background in the places of permanent deployment of the (X) Armed Forces - barracks and their surrounding areas, to determine the effective and collective doses of radiation exposure to personnel, and in this context to study their morbidity, to plan appropriate health-improving measures and their practical implementation
