Teratogenicity01:07

Teratogenicity

2.4K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Biological Effects of Radiation02:59

Biological Effects of Radiation

15.3K
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...

Area of Science:

  • Medical Physics
  • Occupational Health
  • Radiation Safety

Background:

  • Medical facilities utilize ionizing radiation for patient care.
  • Regulatory limits exist for full-term fetal radiation doses.
  • Lack of clear guidance for pre-declaration fetal dose estimation.

Purpose of the Study:

  • To provide a process for estimating pre-declaration fetal doses.
  • To offer a predictive screening tool for licensees.
  • To guide medical licensees in fetal dose evaluations for declared pregnant workers.

Main Methods:

  • Development of a fetal dose estimation process.
  • Creation of a predictive screening tool for workload adjustment recommendations.
  • Guidance for medical licensees performing fetal dose evaluations.

Main Results:

  • A defined process for estimating pre-declaration fetal doses is presented.
  • A predictive screening tool aids in recommending workload adjustments.
  • The evaluation process serves as a guide for licensees.

Conclusions:

  • The presented method and tool address the need for pre-declaration fetal dose estimation.
  • Medical facilities can utilize this guide to manage radiation safety for pregnant workers.
  • Proactive workload adjustments can help prevent exceeding derived investigation levels.
