Part of the position that the worker has a runtime krachoeng radiation measured 0 µR so. Where the operator should stand if necessary it is 90 degrees and 135-corner position, which is the most dangerous corner of 0 degrees.
The actual use for the worker Radiation dose is measured as 0 μR so for the worker to stand in the corner if necessary, it is 90-135 degrees, and for the most dangerous in the corner 0. degree
The position of the worker works actually radiation scattering is measured from 0 R so position that practitioners should stand if necessary, that is at the corner 90-135 degrees. And the most dangerous position at an angle 0 degrees.
