Normaalkiirgus
Normaalkiirgus, also known as normal radiation, refers to the background radiation that is present in the environment at all times. This radiation is a result of natural sources such as cosmic rays from space, radioactive elements in the Earth's crust, and even the human body itself. The primary types of radiation involved in normaalkiirgus are alpha particles, beta particles, and gamma rays. Alpha particles are the least penetrating and can be stopped by a piece of paper, while beta particles are more penetrating and can be stopped by a thin sheet of metal. Gamma rays are the most penetrating and can only be stopped by thick layers of lead or concrete.
The level of normaalkiirgus can vary depending on the location and the specific sources present. For example,
While normaalkiirgus is a natural and unavoidable part of life, it is important to monitor and manage
