摘要
不了解核的人们,总是把核与辐射联系在一起,对核抱有紧张与恐惧的心理。其实辐射是无处不在的,在我们受到的所有辐射照射中,有80%以上来自天然辐射源,只有不到20%来自人工辐射源,而且人工辐射源主要来自医学应用。人们每年受到的天然本底辐射约为2.4 mSv。
For ordinary people,when it comes to nuclear,radiation occurs to their mind,for fear of nuclear.In fact,radiation is almost everywhere.More than 80 percent of our exposure is from natural sources and only less than 20 percent is human made-mainly from radiation applications used in medicine.The dose we absorb from natural background radiation is about 2.4 mSv per year.
