Abstract
The Earth was highly radioactive four billion years ago when life emerged. Even today, all humans are bombarded by 20,000 radiation strikes each second. Although high radiation doses are hazardous, organisms have evolved not only to tolerate lower-dose radiation but also to benefit by it (hormesis). Hormesis is prevailing in all species in various respects. An example is that hibakusha (Japanese A-bomb survivors) have longer lifespans and have lower risk of cancer, on average. Many microbes thrive in deep subsurface regions by consuming radiation as a source of nutrition. Low-dose radiation (LDR) is effective at treating severely affected COVID-19 patients, but the invalid linear no-threshold model (LNT) hinders the full beneficial use of LDR.
期刊介绍:
The aims and scope of Current Opinion in Toxicology is to systematically provide the reader with timely and provocative views and opinions of the highest qualified and recognized experts on current advances in selected topics within the field of toxicology. The goal is that Current Opinion in Toxicology will be an invaluable source of information and perspective for researchers, teachers, managers and administrators, policy makers and students. Division of the subject into sections: For this purpose, the scope of Toxicology is divided into six selected high impact themed sections, each of which is reviewed once a year: Mechanistic Toxicology, Metabolic Toxicology, Risk assessment in Toxicology, Genomic Toxicology, Systems Toxicology, Translational Toxicology.
