Radiology staff are often exposed to low doses of X-rays over long periods. A recent study looked at how this affects their thyroid function and blood cell counts. Researchers studied 136 workers in radiology and related fields. They measured thyroid hormones and blood cell counts to see if there were any changes.

The study found that thyroid-stimulating hormone (TSH) levels varied depending on the worker's job role. Those who worked more hours had different levels of T3, a thyroid hormone. Interestingly, the structure of the thyroid gland didn't show any changes. The study also found that radiologists had higher red blood cell distribution width (RDW-CV) compared to other staff. This means their red blood cells varied more in size.

Gender also played a role in blood cell counts. 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. These findings suggest that long-term exposure to low-dose X-rays might affect thyroid function and blood cell production. However, more research is needed to understand the exact mechanisms and improve safety measures.

The study raises important questions about the health of radiology workers. It's clear that more research is needed to fully understand the effects of low-dose X-ray exposure. In the meantime, it's crucial to follow safety protocols to minimize risks.
