Ionizing radiation energy is generally expressed in units of electron volts (eV), typically as kiloelectron volts (keV) or megaelectron volts (MeV) (Seltzer et al., 2011). Linear energy transfer The ionization patterns produced by different charge particles (e.g., electrons, protons, ...
A third layer (42), consisting of aluminium, is provided for absorbing the alpha and beta radiation. Gaseous fission products are retained by a fourth layer (44) consisting of a zirconium alloy. The absorption casing provided with these layers is used for absorbing the radioactive radiation and...
A free field above a perfectly reflecting, horizontal plane is a simple acoustic environment that closely approximates the actual environment of some sound sources. Compared to a completely free field, however, the radiation of sound from a source above a reflecting plane is more complicated because...
