WebHuman fetal fibroblasts exposed to x-ray irradiation (2 and 4 Gy) showed no significant changes in global 5-hmC level (Wang et al., 2024), indicating that the effect of ionizing radiation on 5-hmC changes or TET protein expression may vary considerably among the types of ionizing radiation. Web27 feb. 2024 · Ionizing radiation is the term given to forms of radiation that are energetic enough to displace orbiting electrons from the atoms in the absorbing medium, thus forming positive ions. The process of ionization is the principal means by which ionizing radiations dissipate their energy in matter and thus may cause biomolecular damage. foot stool tool box
