The construction site of my uncle's company will be inspected 20~50m away. The boss also said there was no harm. Is it true?/You don't say.

X-ray machines are divided into circumferential and directional ray machines.

If the studio here is a flaw detection room qualified by the national environmental protection department, then this distance is not a big problem.

If it's just an ordinary room, it's no problem to use the orienter at a distance of 50 meters as long as it's not directly exposed to your uncle's room.

I list the problems as follows: (only for ordinary rooms that have not passed the safety assessment of the environmental protection department)

1, y ray source

2. Circular X-ray machine

3. Directional X-ray machine: Your uncle's room is exposed directly or obliquely (your uncle's room is within the range of directional X-ray machine).

Anything else, please go to Baidu Post Bar -NDT and leave a message to ask questions.
