Biological Effects of Radiation02:59

Biological Effects of Radiation

16.3K
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...

Radiation: Applications

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 average...

Positron Emission Tomography01:29

Positron Emission Tomography

6.2K
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...

Isotopes and Radioisotopes

10.4K
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.
An isotope containing...

Radiation Pressure: Problem Solving

504
The radiation pressure applied by an electromagnetic wave on a perfectly absorbing surface equals the energy density of the wave. The wave's momentum also gets transferred to the surface when an electromagnetic wave is entirely absorbed by it. The rate at which momentum is transmitted to an absorbing surface perpendicular to the propagation direction equals the force on the surface.
The average value of the rate of momentum transfer divided by the absorbing area represents the average force...

Area of Science:

  • Medical Physics
  • Occupational Health
  • Radiation Protection

Background:

  • Occupational exposure data are crucial for understanding radiation risks to workers.
  • Analysis of exposure trends informs regulatory guidance and enhances safety systems for personnel and the environment.

Purpose of the Study:

  • To analyze occupational radiation exposure data from 2004-2018.
  • To predict future trends in occupational exposure for diagnostic radiology and nuclear medicine.
  • To identify areas for regulatory focus to improve radiation safety.

Main Methods:

  • Collected and analyzed 1,951,486 occupational dose data points from 2004-2018.
  • Utilized SPSS statistical software for data analysis.
  • Estimated annual collective effective dose, average annual effective dose, individual dose distribution ratio, and annual collective dose distribution ratio, as recommended by UNSCEAR.

Main Results:

  • Predicted an 80% increase in monitored workers and a 76% rise in average collective dose for diagnostic radiology by 2023, with no significant change in average annual effective dose.
  • Projected a 28% increase in radiation workers and a 24% rise in collective dose for nuclear medicine by 2023, with no significant change in average annual effective dose.
  • Identified specific reasons and regulatory focus areas for different radiation application practices.

Conclusions:

  • Occupational radiation exposure is projected to increase in key medical fields.
  • The findings provide a basis for targeted regulatory interventions to enhance radiation safety.
  • Continuous monitoring and analysis are essential for effective radiation protection strategies.
