Low-Dose X-Rays: What's Happening Inside Radiology Workers?
Sun Jul 06 2025
Radiology staff are frequently exposed to low doses of X-rays over extended periods. A recent study delved into the potential impacts on thyroid function and blood cell counts.
Study Overview
- Participants: 136 workers in radiology and related fields
- Measurements: Thyroid hormones and blood cell counts
Key Findings
Thyroid Function
- Thyroid-Stimulating Hormone (TSH): Levels varied by job role.
- T3 Hormone: Workers with more hours showed different levels.
- Thyroid Gland Structure: No changes observed.
Blood Cell Counts
- Red Blood Cell Distribution Width (RDW-CV): Radiologists had higher values, indicating more variation in red blood cell size.
- Gender Differences:
- Men and women had different levels of lymphocytes, hemoglobin, red blood cells, and hematocrit.
- For men, white blood cell counts and mean corpuscular hemoglobin concentration (MCHC) changed with longer working hours.
Implications
- Long-term exposure to low-dose X-rays may affect thyroid function and blood cell production.
- More research is needed to understand the exact mechanisms and improve safety measures.
Conclusion
The study underscores the importance of further research to comprehend the health impacts on radiology workers. Adhering to safety protocols remains crucial to mitigate risks.

questions
How do the findings of this study compare with previous research on the effects of low-dose radiation exposure on thyroid function and blood parameters?
If radiologists have higher RDW-CV, does that mean they're just more 'well-rounded' professionals?
Is it possible that the fluctuations in WBC and MCHC are caused by a yet-to-be-discovered environmental factor?
