Mathematical simulation of dose-effect relationships for fish eggs exposed chronically to ionizing radiation.

abstract：:Exposure to ionizing radiation has well-documented long-term effects on cancer rates and other health outcomes in humans. While in vitro experimental studies had demonstrated that the nature of some radiation effects depend on both total dose of the radiation and the dose rate (i.e., the pattern of dose distribution o...
