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.
What deflects gamma radiation?
Thick, dense lead deflects gamma radiations.
What will stop gamma rays?
gamma rays can be stop by lead block
What stops gamma decay?
Lead
Why does lead block radioactivity?
Lead is applied as shielding to block (attenuate is the word we prefer) gamma rays. This form of radiation is electromagnetic in nature, and not particulate (composed of particles). Materials of high density (and lead is fairly high) are better at attenuating gamma rays than less dense materials. Additionally, lead is cheap and easy to work with. You've doubtless heard of lead being used to shield against X-rays, which are just a bit lower in frequency than the gamma rays.It is the "close spacing" of the atoms and the "bigness" of the atomic nuclei of lead that make it good for use in gamma ray shielding. Gamma rays "cut right through" electron clouds around atoms, and only the nuclei of atoms really give the gamma ray something to interact with. As regards particles, lead will stop alpha and beta radiation with ease, but so will a sheet of aluminum foil. Lead isn't that great at stopping neutron radiation. Shielding for neutrons requires atoms with small nuclei, so lead isn't so hot in that application.
What is the best protaction against gamma rays?
A good thickness of lead.

What is an approximate linear absorption coefficient of steel?
linear absorption coefficientAccording to the results of a laboratory experiment I did, the gamma-ray linear absorption coefficient for aluminum is about 10m^-1, and for lead is about 48m^-1, so considering steel is roughly twice the density of aluminum, I'd guess it would be about 20m^-1, however this experiment is not confirmed.

Lead
Can gamma rays be stoped by something?

What is required to shield gamma rays?
A thick layer of lead is the bes shield for gamma rays
Do gamma rays go through thin plastic?
Short Answer:Gamma rays go through most light materials, such as plastic, building materials and are effectively diminished by heavier materials such as lead. It depends on the energy of the gamma ray, but the amount of radiation can often be cut in half by one centimeter thickness of a heavy metal. One centimeter of plastic or wood does not stop more than a few percent of the radiation.Specific Examples:To a rough approximation, the mass density of the material determines how well it blocks gamma rays, not just the thickness. Lead has a density over 11 times greater than water, so one inch thickness of lead should be worth 11 inches for shielding gamma rays. In the table below, you can see lead actually does even better. The thickness necessary to reduce gamma radiation by half is listed with the density of the material in parentheses.lead 1.0 cm (11.3 g/cm^3steel 2.5 cm (7.86 g/cm^3concrete 6 cm (3.33 g/cm^3soil 9 cm (1.99 g/cm^3water 18 cm (1 g/cm^3)wood 302 cm (0.56 g/cm^3)air 15000 cm (0.0012 g/cm^3)Gamma rays can have any energy, so these numbers not equally good for all gamma rays, but work for the sort of radiation humans might encounter due to radioactivity on Earth.See related links and questions for more.
Will gamma radiation pass through plastic wrappers?
Yes, Gamma rays can pass through a metal sheet.Gamma rays are the most penetrating of the radiations.Gamma rays are highly energetic waves.It cannot be said that a particular thickness of a material can absorb all gamma radiation.Many centimeters of lead or many meters of concrete are required to absorb high levels of gamma rays.
What will block gamma radiation?
a thick layer of lead
