Abstract
BACKGROUND: Medical radiation workers are potentially at a risk of unwanted ionizing radiation
exposures. This study assessed the radiation protection knowledge, attitude, and practice (RP‑KAP)
of health‑care workers who are occupationally exposed to radiation regarding protecting themselves
from radiation.
MATERIALS AND METHODS: This study was cross‑sectional in design and was carried out in 16
hospitals affiliated to the Tehran University of Medical Sciences between May and September 2014.
Total health‑care workers who were occupationally exposed to radiation comprising 670 individuals
were included in the study based on census sampling method. In total, 413 individuals consented
to complete an anonymous 32‑item questionnaire comprising single best choice questions with a
numerical value assigned to each correct answer. Each set of RP‑KAP questions was scored and
categorized as poor, medium, and good. The effect of independent variables for prediction of RP‑KAP
was explored using linear regression analyses.
RESULTS: A significant number of participants had poor RP‑knowledge (78.9%), RP‑attitude (70.7%),
and RP‑practice (32.4%). Based on linear regression analyses, it was found that field of study (β = 0.1,
P = 0.001), marital status (β = −0.14, P = 0.01), and level of education (β = 0.2, P < 0.001) were the
predictors of higher RP‑knowledge. In‑service RP‑training (β = 0.1, P = 0.04) was associated with
an increased RP‑attitude. Being a woman (β = 0.2, P < 0.001) and longer years of experience with
radiation (β = 0.2, P < 0.001) were significantly related to better practice.
CONCLUSION: In‑service training with appropriate qualified and up‑to‑date materials based on
radiation workers’ educational needs and approved protocols and guidelines is recommended.
