Negligible and non-negligible risks in radiodiagnostic examination of patients.
Ionizing radiation is regarded as a health hazard, but one is prepared to neglect this factor on the basis of certain motives. In 1975, KNOX published an analysis of these motives, none of which proved tenable. He concluded that a situation which in daily usage is described as safe, is one which entails risks considered to be negligible so that no safety measures are taken. It can be empirically established that in various health-endangering situations a health hazard of less than 1 X 10(-5) is being neglected. This article studies the risk factors to the individual patient in radiodiagnostic examinations involving low, medium and high radiation exposures. The estimates show that radiohygenic measures on behalf of the patient are advisable.
