Biological Effects of Radiation

Biological Effects of Radiation

All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they produce ions...

Neurosurgical Review

|March 19, 2024

Summary

Biologically effective dose (BED) correlates with tremor improvement in stereotactic radiosurgery for essential tremor (ET). Adjusting radiation dose, not cobalt-60 sources, is recommended to optimize ET treatment outcomes.

Area of Science:

Neurosurgery
Radiation Oncology
Medical Physics

Background:

Essential tremor (ET) management often involves stereotactic radiosurgery (SRS).

Keywords:

Biologically efective dose Essential tremor Radiosurgery TETRAS
