Atmost any material can act as a shield from gamma or x-rays if used in sufficient amounts. Different types of ionizing radiation interact in different ways with shielding material. The effectiveness of shielding is dependent on stopping power, which varies with the type and energy of radiation and the shielding material used. Different shielding techniques are therefore used depending on … WebApr 13, 2024 · The main (but very slight) difference between SPF 30 and SPF 50 sunscreen is the percentage of UVB rays it blocks. Even though a higher SPF can be misleading, Dr. Garshick says “there is some added benefit to SPF 50, as SPF 50 blocks 98 percent of UVB rays.” SPF 30 sunscreens, on the other hand, block 97 percent of UVB rays.
