What is Radiation Safety?

Medical radiation comes from X-ray-using radiography, CT, fluoroscopy, and nuclear medicine studies. Compared to daily natural background radiation, the dose of a single study generally remains low.

The ALARA (As Low As Reasonably Achievable) principle requires the justification of every study, optimization of the dose, and avoidance of studies that do not contribute to treatment.

Symptoms

Low-dose medical radiation has no acute symptoms
Very high doses cause acute radiation syndrome (not expected in medical imaging)
Long-term high cumulative dose may theoretically increase cancer risk
Fetal exposure carries developmental risk
Radiation sensitivity differs from person to person
Children are more sensitive to radiation than adults

Risk Factors

Multiple CT or fluoroscopy studies in a short time
Pregnancy (especially first trimester)
Pediatric age group
Genetic syndromes with increased radiation sensitivity
Occupational radiation exposure (radiology workers)
Unnecessary repeat imaging

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Ask your doctor why each study is necessary and whether there are alternatives
  • Inform before the study if you are pregnant or might be
  • Radiation-free alternatives (US, MR) can be questioned for your child
  • Workers with occupational radiation exposure should be followed with dosimeters

Treatment Methods

01
Avoidance of unnecessary radiation through the ALARA principle
02
Use of protective abdominal apron in pregnancy
03
Low-dose protocols and preference for MR/US when possible in children
04
Adherence of radiologists to dose optimization protocols
05
Annual dose follow-up and limit auditing for occupational workers
