Beta Therapy

Beta therapy is a type of radiation therapy based on the effect of beta radiation of radioactive isotopes on pathologically altered tissues.

Beta therapy uses radioactive isotopes that emit beta particles. These particles are a stream of electrons or positrons. They have low penetrating ability and are absorbed by tissues at a shallow depth.

Beta radiation has an ionizing effect on cells, which leads to the destruction of DNA in pathologically altered cells. This causes cancer cells to die or stop growing.

Beta therapy is widely used to treat various cancers, including skin, thyroid, and prostate cancer. It can be used either as monotherapy or in combination with other treatments, such as surgery or chemotherapy.

The advantages of beta therapy are its high efficiency, the possibility of local impact on the tumor, as well as the relatively low radiation dose to healthy tissue compared to other types of radiation.

**Beta Therapy:** Beta (beta) is a cross between alpha and gamma particles. The number of protons in the nucleus of an α-particle is 4, and in a γ-particle it can reach several tens, up to 2. And in β-particles the number of protons reaches two dozen, just from 3 to 8. These are very light, unstable particles that are formed in the nuclei of atoms during nuclear reactions. Some beta particles jump out due to beta decay or β − -accompanied alpha decay of atomic nuclei under the influence of an external field applied during beta activation to the nuclear reactions from which these rays are emitted. Beta rays are also electrons; a positive beta ray passing through a substance bombards it from the outside and excites the atom
