   May 7, 2024 · Equivalent dose (symbol HT) is a measure of the radiation dose to tissue where an attempt has been made to allow for the different relative biological effects of different types of ionizing radiation. In quantitative terms, equivalent dose is less fundamental than absorbed dose, but it is more biologically significant.

   What is effective dose 50?

   • Effective dose 50 (ED50) is the dose to induce a prescribed level of radiation injury in 50% of the test animals. The main difference between the RBE and the CBE factor calculation is in the absorbed radiation dose. In the determination of the RBE, the actual radiation dose to the tissue is applied.
