In physics,
radiation is a process in which energetic particles or energy or waves
travel through a medium or space. There are two distinct types of radiation;
ionizing and non-ionizing. The word radiation is commonly used in reference to
ionizing radiation only (i.e., having sufficient energy to ionize an atom), but
it may also refer to non-ionizing radiation. The energy radiates from its
source. This geometry naturally leads to a system of measurements and physical
units that are equally applicable to all types of radiation.
Both ionizing and non-ionizing radiation can be harmful to organisms and can
result in changes to the natural environment.
Tungsten is used in many radiation shielding applications including industrial, nuclear and medical. Because of its high density and high atomic number, is an effective construction material for shielding from gamma rays and x-rays. Lead and boron carbide can shield radiation too, But can’t performance as good as tungsten alloy
