WebApr 12, 2024 · Gamma Knife is not a knife, but rather a sophisticated system that can be used instead of brain surgery or whole brain radiation in some situations. It uses a single, high dose of gamma radiation to treat brain lesions with enough radiation to control them, so that they disappear, shrink or stop growing. WebJul 1, 2024 · Lead is very good at stopping gammas but not good for construction. Brick would be better than wood. For gamma ray energies less than 10 MeV the brick would stop a large percentage of gammas. But that percentage would go down as energy goes up. You can probably find tables of attenuation coefficients on the internet.
