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...

Summary

This summary is machine-generated.

Staff in endourology operating theatres experience significant scatter radiation exposure, particularly urological surgeons and surgical nurses. This occupational health hazard requires further investigation to ensure staff safety during fluoroscopic procedures.

Area of Science:

Medical Physics
Occupational Health
Urology

Background:

Endourology procedures often involve fluoroscopic guidance, raising concerns about staff exposure to scatter radiation (SCR).
Assessing occupational SCR exposure is crucial for understanding and mitigating potential health risks for operating theatre personnel.

Purpose of the Study:

To investigate and quantify scatter radiation (SCR) exposure among various staff professional groups within the endourology operating theatre.
To analyze the correlation between SCR doses and procedural/patient factors.

Main Methods:

Real-time dosimeters (Philips DoseAware System) were used to measure SCR exposure on the head and chest of five professional groups.
Data were collected from July 2023 to February 2024 during surgeries under fluoroscopic guidance.
SCR data were analyzed and correlated with dose-area product (DAP) and other relevant factors.

Main Results:

A total of 249 procedures were analyzed, including retrograde intrarenal surgeries and percutaneous nephrolithotomies.
Urological surgeons (US) and surgical nurses (SN) exhibited the highest median SCR exposures on their chests and heads.
Significant correlations were found between DAP and SCR doses for multiple staff positions (p < 0.05).

Conclusions:

This study provides novel insights into occupational SCR exposure in endourology using real-time dosimetry.
Substantial SCR exposure levels were identified, highlighting a significant occupational health hazard for endourology staff.
Further research is warranted to develop effective strategies for minimizing radiation exposure and ensuring staff safety.
