生活之中到处都是辐射

顺便提一句，你是否居住在美国本土？1997年，美国国家癌症研究所(National Cancer Institute)发布的报告称，由于放射性碘在空气中的扩散，冷战时期在内华达试验场(Nevada Test Site)进行的核爆炸试验已经对整个国家构成了污染，并导致了10,000例至75,000例儿童甲状腺癌的出现。据美国疾病控制与预防中心(Centers for Disease Control and Prevention)估计，在每年近600,000名死于癌症的美国人中，有11,000名患者的病因是由内华达的核试验导致的。记不记得在冷战的几十年间对苏联使用核武器攻击美国人的担忧？事实上，美国政府用内华达的核试验辐射了美国人民，而苏联政府则用哈萨克斯坦的核试验辐射了苏联人民。

But there is, in all this, some good news.

但是，尽管如此，我还是有一些好消息。

The source of radioactivity is an atom so obese that it defies the laws of attraction gluing together our material world and spits out little pieces of itself -- two kinds of particles and a stream of gamma rays, similar to X-rays. An overdose of gamma rays is like a vicious sunburn, with skin damage and elevated cancer risks, but those particles are too big to penetrate our skin, meaning that they need to be swallowed or inhaled to wreak damage. Remember the movie 'Silkwood,' with Meryl Streep writhing in naked agony as men with brushes scrubbed her in the shower? They were washing away her exposure. The truly fearful event in a nuclear accident, then, isn't fallout but meltdown, where the core burns through the floor and suffuses the water table. There it causes agricultural mayhem and radioactive dust that you better not breathe.
