Deterministic and stochastic effects

According to the International Atomic Energy Agency (IAEA), a health effect that requires a specific level of exposure to ionizing radiation before it can occur is called a deterministic effect. The severity of a deterministic effect increases as the dose of exposure increases and considers a minimum threshold, … See more Stochastic effects are probabilistic effects that occur by chance. An extremely rare stochastic effect is the development of cancer in an irradiated organ or tissue. The probability of occurrence is typically proportional to the … See more In our day-to-day lives, we are exposed to both background and man-made sources of radiation.Everyone receives radiation exposure from natural cosmic and solar rays, and radionuclides in soil.
