What will block gamma radiation?

a thick layer of lead


What is required to shield gamma rays?

A thick layer of lead is the bes shield for gamma rays


What minimum type of shielding is needed to stop gamma radiation?

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.


Which form of radiation will be stopped by a thick layer of concrete or a thick layer of lead?

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.


What deflects gamma radiation?

Thick, dense lead deflects gamma radiations.


What will stop gamma rays?

gamma rays can be stop by lead block


What objects can stop 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 (:


What stops gamma decay?

Lead


Can gamma rays be stoped by something?

Lead.


Does lead stop radiation?

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


What material will stop a gamma particle?

Lead can stop gamma particles really fast because it is so dense. Gamma particles can also be reduced by water.


The most penetrating of the types of nuclear radiation?

Gamma rays. They need layers of concrete and lead. They are also still not completely blocked.
