Risks of Radiation风险的辐射
The energy released by radiation in significant doses can damage the DNA in living cells, yet our bodies carry out a continuous process of repair. Lower doses lead to cells that have repaired themselves incorrectly and which may be at increased risk of developing cancerously owing to these mutations. The body already has cells like this from other causes, but damage from radiation increases the number of cells and therefore the risk of developing cancer over the long term. However, it is important to put the risks from radiation into perspective.释放的能量辐射在显着的剂量可破坏DNA在活体细胞，但我们的身体进行一个持续的过程，维修。较低剂量导致细胞修复了自己的错误，并可能在风险增加发展中国家的cancerously由于这些基因突变。身体已细胞像这样由其他原因，但造成的损害辐射增加细胞数目，因此有可能发展成癌症以上的长远目标。不过，这是很重要的，把风险从辐射的角度来看。
The extra risk of developing cancer from low doses of ionising radiation is so small that it is undetectable in the population. The extra risk from higher doses is just detectable. Even with high doses, it is not always possible to determine if radiation is the direct cause of the cancer because there may be many other factors involved.额外的风险，发展中国家的癌症，从低剂量电离辐射是这么小，这是undetectable在人口。额外的风险较高剂量的只是探测，即使高剂量，这是不总是能够确定，如果辐射是直接造成的癌症，因为可能有很多其他因素的参与。
A lifetime of exposure to all sources of ionising radiation (naturally-occurring and manmade) is thought to amount to an additional risk of contracting fatal cancer of one per cent. This should be compared to a general lifetime risk of cancer of between 20-25% from other causes, such as smoking, poor diet, or exposure to large amounts of strong sunlight.一生接触到的所有来源的电离辐射（自然发生的和人为）被认为是构成额外的风险承包的致命癌症的一％ ，这应该是比较一般的一生患癌症的风险之间20-25 ％来自其他原因，如吸烟，穷人的饮食，或暴露于大量的强烈阳光。
The risk to health of not having medical treatment involving radiation far outweighs the risk of developing serious illness from the procedure itself.风险的健康没有就医涉及辐射远远大于风险，发展中国家严重的疾病，从程序本身。
