辐射防护讲座-东南大学幻灯片.pptVIP

培养要求 本专业学生主要学习四大化学、化工原理、放射化学（辐射化学）、原子核物理、辐射防护、环境工程学、辐射剂量学、核电子学与核仪器仪表、核环境学、反应堆工程、放射性废物处理与处置等基本理论知识和基本技能。掌握辐射监测、辐射防护技术、辐射安全评价、辐射污染防治技术等专业知识，具有从事与辐射防护、核设施安全相关的评价、研究、管理工作的能力。 为什么要办辐射防护与环境工程专业？ 低碳经济发展的需要。二氧化碳的过度排放有可能导致全球气候不可逆的灾难性变化。人类对能源的需求十分巨大，太阳能、风能、燃料电池等新能源虽然取得了飞速发展，能够大规模取代火电、建造百万千瓦以上电站的成熟技术，仍然只有水电与核电。 核技术日益广泛应用的需要。核技术的应用包括核医学、核农学、辐照加工等。 由于辐射的潜在危害，核电与核技术的发展必然要求大量的辐射防护与环境工程专业人才，以保证核工业造福于人类，而不是祸害人类。 毕业后大家的就业如何解决？ 主要就业方向：军队，核电站，各级辐射环境监测站，中核集团的科研单位和企业。 核电站的辐射防护部门大约有十几个编制，在建的核电站目前只有1~2人。 各级辐射环境监测站，尤其是将建有核电站的省份，需要大量的本专业毕业生，编制大约相当于现有编制的十倍。 中核集团需要的毕业生更多。 本专业是一个学科交叉性相当强的专业，如果抓紧时间学习，知识更广泛，眼界更开阔。 谢 谢 大 家 ！ 南 京 理 工 大 学 * * * * * * Discus the main elements and purpose of the crawler equipment and where they may typically be used (onshore and offshore).

The potential for serious injury when using x-ray equipment is very apparent when one considers the dose rate that x-ray equipment can produce. As an a Rigaku 250EGS2 250 kVp directional x-ray unit operating at 250 kVp and 5 mA produced a dose rate in air of approximately 1.2 Gy/min at 30 cm (with 2 mm Al filter). With only the 1mm Be window the dose rate was approximately 10.6 Gy/min at 30 cm.
