Table 2 Summary of correct responses obtained for the five true-false statements relating to radiation protection principles, regulations, and potential for increased radiation risk for paediatric patients

From: Paediatric imaging radiation dose awareness and use of referral guidelines amongst radiology practitioners and radiographers

True–False statements Answer Correct responses, n (%)
Radiology practitioners (n = 12)a Radiographers (n = 100)a
The benefit of performing a medical imaging examination should be similar to the associated risks involved False 11 (91.7) 84 (85.7)
It is estimated that paediatric patients have a 2 to 5 times higher lifetime cancer risk per unit dose of radiation when compared to adults True 10 (90.9) 81 (83.5)
Maltese and European legislation stipulate that each medical exposure to ionising radiation must be justified True 12 (100.0) 99 (99.0)
Optimisation refers to the principle by which each medical radiation exposure must provide the best image quality for diagnosis, irrespective of the radiation dose involved False 9 (75.0) 95 (95.0)
Every single exposure to ionising radiation is cumulative and therefore increases an individual’s lifetime cancer risk True 10 (83.3) 84 (84.0)
