I need the confirmation, is it if we put survey meter at 270 degree, does the reading of scattered radiation is same with 90 degree. In my opinion, the reading would be same as the distance is still same (other factor like kVp, Feild size, thickness are constant). or do we need to considered back scattered radiation as it deflect 180 degree.
my explaination is like this-the reading of survey meter would be like 90°, this is because the location and distance of survey meter from x-ray tube is similar with 90°. However, if the survey metre is placed close to the x-ray tube's anode, the reading may be slightly greater than cathode side. The anode is the component of the x-ray tube that produces x-rays.
