WebJan 12, 2024 · A deterministic (non-random) effect occurs after exceeding a threshold dose, and the severity of the effect correlates with the dose. In radiation protection circles (e.g., NCRP and ICRP), these effects are more recently being referred to as “tissue reactions.” The term is associated with effects that result from damage to many cells.
