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...

To propose future directions for brachytherapy dosimetric audits.

Main Methods:

Review of published literature on brachytherapy dosimetric audits.
Analysis of ongoing brachytherapy audit initiatives.
Discussion of various dosimetry measurement techniques including ionization chambers, TLDs, OSLDs, radiochromic film, and alanine detectors.

Main Results:

Source strength measurement concerns are largely addressed by modern equipment and calibration.
Brachytherapy is a rapidly evolving field necessitating advancements in dosimetric audit methods.
Various detector types have been employed for brachytherapy dose audits, each with specific advantages and limitations.

Conclusions:

Continued development and adaptation of dosimetric audit protocols are essential for brachytherapy.
Future audits must keep pace with technological advancements in brachytherapy.
Standardized and robust dosimetric audits are key to ensuring quality and safety in brachytherapy.
