sisäsäteiden

Sisäsäteiden refers to the internal radiation emitted by a radioactive substance. This type of radiation originates from the nucleus of an atom and can be classified into three main categories: alpha particles, beta particles, and gamma rays. Alpha particles consist of two protons and two neutrons, making them identical to a helium nucleus. They have a low penetration power and can be stopped by a sheet of paper or the outer layer of human skin. Beta particles are high-energy electrons or positrons emitted by certain types of radioactive decay. They have a higher penetration power than alpha particles and can be stopped by a thin sheet of aluminum. Gamma rays are high-energy photons emitted during radioactive decay. They have the highest penetration power of the three types of internal radiation and can only be stopped by thick layers of lead or concrete. The intensity of sisäsäteiden can be measured using various instruments, such as Geiger counters and scintillation detectors. The effects of internal radiation on living organisms depend on the type and amount of radiation absorbed. Prolonged exposure to high levels of internal radiation can lead to radiation sickness, cancer, and other health issues. Proper shielding and safety measures are essential to minimize the risks associated with internal radiation exposure.
