I would like to ask, like the EPA's detection of nuclear radiation equipment itself will be radioactive? Long-term impact on the body of the large

First of all, to make it clear that the radiation you are referring to is ionizing radiation, rather than other electromagnetic waves and other radiation, and secondly, there is no radioactivity in this thing, we first analyze the source of radioactivity. 1, natural sources of radiation. 2, machine sources are also ray machines, accelerators and the like. 3, reactors, you said the EPA detection of radiation equipment itself will have radiation? 2, the machine source is also on the ray machine, gas pedal of a class. 3, the reactor, you said the EPA radiation detection equipment, obviously does not belong to these three categories, in addition to the radioactivity from the monolithic either it is a radioactive source, or it has a sense of radioactivity. The above exclude the possibility of radioactive sources, then next we analyze whether it will have a sense of radioactivity, with a sense of radioactivity there are three cases: 1, neutron activation, the specific definition of their own check, neutron radiation can only be by the elemental decay, nuclear reactions and high-energy reactions (such as cosmic clusters of radiation or particle gas pedal collisions), if the EPA has a reactor, well, that's good, the Bureau of where I have to go to work. 2, photometamorphosis, the definition of which I will go to work. 3, photometamorphosis, the definition of which is not a part of the three categories. The first thing I'd like to say is that I don't know where to start, but I'd like to know where to start, and I'd like to know where to start, and I'd like to know where to start, and I'd like to know where to start, and I'd like to know where to start, and I'd like to know where to start, and I'd like to know where to start, and I'd like to know where to start, and I'd like to know where to start, and I'd like to know where to start, and I'd like to know where to start, and I'd like to know where to start, and I'd like to know where to start, and I'd like to know where to start: Induction cooker is directly above the existence of a very strong radiation oh
