Background:
- Peripheral dose measurement is critical for patient safety in electron beam radiation therapy.
- Accurate dosimetry ensures precise radiation delivery and minimizes risks to healthy tissues.
Approach:
- A systematic literature review adhering to PRISMA standards was conducted.
- Searched PubMed, Web of Science, and Scopus for studies from 1978 to July 2023.
- Focused on peripheral dose analysis across various electron beam parameters and equipment manufacturers.
Key Points:
- Seven articles were included, detailing strategies to reduce peripheral dose.
- Techniques include using bolus materials, custom cutouts, and optimized treatment protocols.

15.4K
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...

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

The electromagnetic spectrum consists of all the types of electromagnetic radiation arranged according to their frequency and wavelength. Each of the various colors of visible light has specific frequencies and wavelengths associated with them, and you can see that visible light makes up only a small portion of the electromagnetic spectrum. Because the technologies developed to work in various parts of the electromagnetic spectrum are different, for reasons of convenience and historical...
