孕妇从小处入手防辐射

日本大地震造成福岛核电站事故核泄漏引起的辐射，让很多人感到恐慌。不少孕妇为了保护腹中的宝宝。整天穿着防辐射服以强化防护。为此．有关人士提醒说——     

是盐荒,还是心慌?

九级地震同时引发的海啸,让日本福岛核电站发生了核泄漏。就在日本人发放碘片用于防治核辐射时,中国却出现了抢购食盐的闹剧。抢购理由大致有两个:一是因为食盐中有碘,可以抗辐     

核电站会像原子弹一样爆炸吗?

核反应堆是不可能像原子弹那样爆炸的。这个结论的原因很简单:核反应堆的燃料铀不纯,它们没有能力产生原子弹式的爆炸。虽然核弹和核反应堆都是以铀为原料,但两者对纯度的要求完全不同,从地下挖出来的天然铀含99.3%的铀238和只     

独家赠送《微本大利速富法》

以美国为首的北约在轰炸南联盟时使用的“贫铀弹”，将对人身健康造成无穷后患，所谓“贫铀弹”，是比一般武器多了放射性物质铀的炮弹。天然铀经过核工业技术分离，把供棱武器、核电站用的铀-235、铀-234除去后，剩下的废料是铀-238。     

秦山核电站运行对上海环境放射性影响评价

Objective To study the effect on the environmental radioactivity level and the health of the residents in Shanghai when Qinshan Nuclear Power Station(QNPS) has been in normal operational condition for 17 years. Methods The field monitoring and the sampling analytical method were used for monitoring the radioactivity level in outdoor environment, drinking water, food and soil. Results The outdoor natural radiation level and the radioactivity level in the sample of the environmental media were on the normal background level. There was no distinct change in the environmental radiation level of Jinshan Area when QNPS was in normal operational condition. The radioactivity level in the environmental media was far lower than the limit values specified by the national standard GB. The effective dose of the outdoor natural external exposure for the residents is about 0.102 mSv/a and the effective dose of the internal exposure from the artificial radionuclides 90Sr and 137Cs in food for the residents is about 0.488 μSv/a. Conclusions There is no effect of the radioactive contamination on the environmental radioactivity level and the health of the residents in Shanghai when QNPS has been in normal operational condition for 17 years.

海南昌江核电站周围环境饮用水放射性本底调查

目的通过开展在建的海南昌江核电站周围环境饮用水放射性监测,建立该核电站周围环境饮用水放射性基线数据库。方法采用饱和厚度相对测量法,总α、总β分别用厚样法、薄样法。结果总α、总β范围分别为(0.0001~0.0944)Bq/L和(0.0140~1.1029)Bq/L,几何均数分别为0.0028 Bq/L和0.0513 Bq/L;地下水总β比地表水高,差别有统计学意义(t=3.319,P0.05);水源水总α、总β略高于出厂水;井水、泉水总α、总β比出厂水高,差别有统计学意义(t=2.146、3.301,P0.05);井水、泉水总β较末梢水高,差别有统计学意义(t=2.861,P0.05);分散式供水总α、总β比集中式高,差别有统计学意义(t=2.355、3.293,P0.05);枯水期总α比丰水期高,差别有统计学意义(t=9.876,P0.05)。结论昌江核电站周围环境大部分饮用水样品总α、总β放射性水平符合国家生活饮用水标准;总α、总β在海南省饮用水正常放射性本底水平内,且与国内其它地区相比处于相对低的水平。     

切尔诺贝利事故后低剂量辐射对血液系统的影响

切尔诺贝利核电站事故后，人血液系统发生了变化。受１Ｇｙ以内辐射的参加消除事故人员，１年以后出现白细胞数异常，事故后３年发生某些白细胞核的光密度改变。消除事故中有４１．５％直升飞机驾驶员在照后一周被诊断为各种临床综合征，事故后５￣６年血液各类白细胞发生质和量的改变。６年后各类淋巴细胞比例和形态图像发生了很大变化。并在照射后不同时期，分别出现红细胞，血红蛋白，血小板质和量的改变。     

核电站正常运行时的放射防护目标值

本文讨论了核电站正常运行时的放射防护目标值。首先是简要叙述了目标值概念的发展和含意,接着就公众照射和职业照射中的个人剂量与集体剂量,给出了一些有关数据,并在此基础上对制定相应的目标值提出了建议。     

9大症状显示你被辐射了

日本强震引发核泄漏,核安全问题成为人们关注的焦点。中国核电安全专家表示,日本原子能机构将福岛县第一核电站爆炸事故级别定为4级,以后又升为5级。那么,核辐射究竟对健康会造成什么影响?如果有以下9个症状,那很有可能你被辐射了!
