Radiation Protection Dosimetry
|December 31, 2019
Summary
Electronic personal dosemeters (EPDs) and survey meters are increasingly used in radiation dosimetry. This review examines their performance and potential concerns, particularly in pulsed X-ray fields and varying energy responses.
Area of Science:
- Radiation protection and dosimetry
- Medical physics
- Nuclear instrumentation
Background:
- Radiation protection relies heavily on dosimetry instrumentation, with passive dosemeters historically dominating personal and area monitoring.
- Survey meters are established for dose rate measurements, but electronic personal dosemeters (EPDs) are emerging as potential replacements for legal monitoring.
- Concerns regarding EPDs and survey meters include their response to pulsed X-ray fields and energy dependency.
Purpose of the Study:
- To review recent literature on electronic dosemeters for strongly penetrating photon radiation.
- To analyze the technologies, performance, and future outlook of contemporary EPDs and survey meters.
Main Methods:
- Literature review of scientific publications on electronic dosimetry.
- Analysis of performance data for EPDs and survey meters in various radiation fields.
- Discussion of technological advancements and emerging concerns.
Main Results:
- Electronic dosimetry technologies in contemporary EPDs and survey meters are diverse.
- Performance evaluations highlight specific challenges, including pulsed fields and energy response variations.
- Future perspectives involve addressing these limitations for broader adoption.
Conclusions:
- EPDs and survey meters show promise but require further development to overcome performance limitations.
- Continued research is essential for reliable electronic dosimetry in diverse radiation environments.
- The transition from passive to electronic dosimetry necessitates careful consideration of accuracy and reliability.

17.5K
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...

In the early 1900s, English chemist Frederick Soddy realized that an element could have atoms with different masses that were chemically indistinguishable. These different types are called isotopes — atoms of the same element that differ in mass. Isotopes differ in mass because they have different numbers of neutrons but are chemically identical because they have the same number of protons. Soddy was awarded the Nobel Prize in Chemistry in 1921 for this discovery.

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...

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.

The most common types of radioactivity are α decay, β decay, γ decay, neutron emission, and electron capture.
Alpha (α) decay is the emission of an α particle from the nucleus. For example, polonium-210 undergoes α decay:
