Radiation辐射

Radiation is the energy produced by certain manmade materials, and by naturally-occurring radioactive minerals underground (sometimes known as low level ‘background radiation’).辐射是能源所产生的某些人工材料,由自然发生的放射性矿物地下(有时也被称为低的水平â € 〜背景radiationâ € ™ ) 。

There are two types of radiation: ionising and non-ionising. Non-ionising radiation is safe, but ionising radiation is potentially harmful.有两种类型的辐射:电离和非电离。非电离辐射是安全的,但电离辐射是潜在有害的。

Non-ionising radiation is found in the environment in sunlight, power-lines, electrical equipment and mobile phone systems which do not have enough energy to produce harmful ionising radiation.非电离辐射被发现在该环境中的阳光,电源线,电气设备和移动电话系统,没有足够的能源产生有害的电离辐射。

Ionising radiation includes radiation from space that passes into the atmosphere, from medical testing, and industrial and weapons testing.电离辐射,包括来自太空的辐射传递到大气中,从医学测试,以及工业和武器试验。
