It is lead’s density and large number of electrons, which make it particularly suited to scattering x-rays and gamma-rays. These rays from photons, a type of boson, impart energy onto electrons upon contact. When the radiation attempts to pass through lead, its electrons absorb and scatter the energy.
WebNov 28, 2009 · Answer. Chris - Well, the reason that lead is a good choice is because it's a very dense substance, because dense substances can get in the way of the radiation and soak it up. And the denser something is the more atoms they have; in the case of things …
WebApr 7, 2011 · Buessler and other experts say this much is clear: Both short-lived radioactive elements, such as iodine-131, and longer-lived elements — such as cesium-137, with a half-life of 30 years — can be absorbed by phytoplankton, zooplankton, kelp, and other marine life and then be transmitted up the food chain, to fish, marine mammals, and humans. dwayne christopherWebRF radiation has lower energy than some other types of non-ionizing radiation, like infrared and visible light, but it has higher energy than extremely low-frequency (ELF) radiation.
