Radiation hormesis hypothesis compared with LNT and linear model with threshold. In all 3<br />
graphs, x-axes represent radiation dose and y-axes represent magnitude of health effect. Zeroequivalent<br />
point (ZEP) represents level of health effect in absence of radiation. The quadratic<br />
model of Figure 1 approximates threshold graph of this figure. A threshold model would imply<br />
no effects of radiation up to certain level, after which risk rises linearly with dose. The radiation<br />
hormesis model, in contrast, shows beneficial effect at low levels of exposure as it drops below<br />
ZEP.<br />
