Answer» Right OPTION is (a) 50 mm To elaborate: X-rays are considered to be having a larger wavelength as compared to that of gamma rays. Owing to this fact, the penetration power of the X-rays is less. Hence, for a shorter thickness, it would give good detection. The best RESULTS are OBTAINED in X-ray detection when the thickness of the MATERIAL is below 50mm.
