One is a high radiation station baggage screening X-ray machine. This kind of equipment because it is a multi-energy detection source, and in the work of the need to penetrate the thick steel plate, so his ray source of the work load is very large, will produce a certain amount of X-ray radiation. But because the baggage security machine are made of anti-radiation treatment, so in the baggage security check is not to put your hand into the X-ray machine inside.
There is also what we usually call a medical X-ray machine. Because this kind of machine is to use low energy, the general are between fifty to two hundred and fifty milliamps, so he will not produce any radiation on the human body.
