Local Radiolesion in X-Ray Inspection Specialists

Area of Science:

• Medical Physics
• Radiation Oncology
• Biomedical Engineering

Background:

• Accidental radiation exposure can cause significant tissue damage.
• X-ray inspection plants require precise installation to prevent safety breaches.
• Understanding radiation dose-response is critical for occupational safety.

Observation:

• Two laboratory workers sustained acute local radiation injuries (LRs) to their hands from an X-ray inspection plant installation error.
• Patient 1 presented with severe to extremely severe LRs, while Patient 2 had mild LRs on the right hand.
• The incident involved the 'Extravolt-225/1600' X-ray inspection plant.

Findings:

• Severe LRs in Patient 1 were treated with surgery and autologous mesenchymal stem cell transplantation.
• Mild LRs in Patient 2 were managed with conservative treatment.
• Both patients achieved complete epithelization of the affected areas.
• Electron Paramagnetic Resonance (EPR) analysis of bone structures helped reconstruct the exposure's spatial-temporal characteristics.

Implications:

• This case highlights the importance of stringent safety protocols during the installation and operation of high-energy X-ray equipment.
• Mesenchymal stem cells show promise in treating severe radiation-induced skin injuries.
• Incident modeling and advanced analytical techniques (EPR) are valuable for understanding radiation accidents and improving safety measures.
