BIOLOGICAL BASIS FOR R ADIATION SAFETY 281 of the dose. Stochastic effects, such as cancer, are also seen among persons with no known exposure to the agent associated with that effect.) and nonstochastic, or deterministic effects. Most biological effects fall into the category of deterministic effects. Deterministic effects are characterized by the three qualities stated by the Swiss physician and scientist Paracelsus about 500 years ago when he wrote “the size of the dose determines the poison.” (A corollary to this is the old adage that there are no harmful chemicals [or radiation], only harmful uses of chemicals [or radiation]): 1. A certain minimum dose must be exceeded before the particular effect is observed. 2. The magnitude of the effect increases with the size of the dose. 3. There is a clear, unambiguous causal relationship between exposure to the noxious agent and the observed effect. For example, a person must exceed a certain amount of alcoholic intake before he or she shows signs of drinking. After that, the effect of the alcohol depends on how much the person drank. Finally, if this individual exhibits drunken behavior, there is no doubt that the behavior is the result of drinking. For such nonstochastic effects, when the magnitude of the effect or the proportion of individuals who respond at a given dose is plotted as a function of dose in order to obtain a quantitative relationship between dose and effect, the dose–response curve A, shown in Figure 7-1, is obtained. Because of the minimum dose that must be exceeded before an individual shows the effect, nonstochastic effects are called threshold effects. Threshold radiation doses for some clinically significant deterministic effects are shown in Table 7-1. Percent Response 100 50 0 a b c Dose Figure 7-1. Dose–response curves. Curve A is the characteristic shape for a biological effect that exhibits a threshold dose—point a. The spread of the curve from the threshold at point a until the 100% response is thought to be due to “biological variability” around the mean dose, point c, which is called the 50% dose. Curve B represents a zero-threshold, linear response. Point b represents the 50% dose for the zero-threshold biological effect being studied. B A
