Radiations from radioactive materials can be dangerous and pose health hazards. Gamma radiation is the most penetrating.

Some propositions of previously published works of the author are developed here as well as the influence of experiment geometry on results of the diffused gamma-radiation method from the point of view of its deepness.

The radiation penetration of protons or alpha particles from a real isotope will be a combination of many of these curves, all of different energies, smoothing out the shape of the curve. The farther away people are from a radiation source, the less their exposure. Depleted uranium is often used as a shielding material for sources. Cobalt cameras are often fixed to a trailer and transported to and from inspection sites. In practice it is very difficult to measure the dose near the surface of material special extrapolation chambers do exist for this. Skempton formulated concepts and porous water coefficients that are still widely used today. Given the initial energy of the particle, the exact final point were the particles slow down and stop can be determined.

Penetration of Different Types of Radiation

Manmade radioactive sources are produced by introducing an extra neutron to atoms of the source material. Figure 1 Radiation enters a slab of something concrete, lead, water, maybe even you and that something has lots of tiny atoms in it the green dots. Porosity in sandstone is qualitatively inferred by observing the ROP in shale and comparing that to the ROP in a known sandstone interval. Conversely, if we lower the radiation energy, the HVL will occur shallower in depth.

Description: This means that without a special detector with a thin window or no window detecting alphas is a non-starter. Interaction Help About Wikipedia Community portal Recent changes Contact page. The absorption of radiation starts as soon as the radiation enters a material. Therefore, the more dense a material, the less the depth of radiation penetration will be.
