Want this question answered?
Gamma radiation has in principle infinite range. So it is not possible to block it completely. But it is possible to attenuate it to certain level. The thickness of concrete needed depends on gamma photons energy and concrete properties.
Gamma rays and X-rays will pass right through paper (which will stop alpha rays) and aluminum sheets (that will stop beta rays), but can be stopped by a thick layer of concrete, lead, or other substances having sufficient mass.
Thick, dense lead deflects gamma radiations.
gamma rays can be stop by lead block
Lead
a thick layer of lead
A thick layer of lead is the bes shield for gamma rays

Gamma rays can be blocked by a thick amount of lead. Alpha -> goes through thin mica -> then stops at skin or paper. Beta -> Goes through thin mica - then goes through skin or paper -> gets stopped at lead. Gamma -> Goes through thin mica -> goes through skin or paper -> then can be slowed down by lead or can be stopped completely by a thick amount of lead. I may have Beta and alpha mixed up but please excuse me as im writing this out of my book (:
Lead
Lead.
Alpha radiation does not pass to paper or skin Beta radiation can easily pass through paper and skin, but not through a Thin sheet of lead (about 3cm)Gamma radiation can pass through all of the above easily, however it can not pass through thick lead (around 3m) and even thicker concrete. People working with gamma radiation have to use robots or wear very heavy, thick lead suites, and they still dont work with them directly
Lead can stop gamma particles really fast because it is so dense. Gamma particles can also be reduced by water.
Gamma rays. They need layers of concrete and lead. They are also still not completely blocked.
