Nearly 80 percent of radiation oncology studies funded by the National Institutes of Health involve investigating the effects that radiation has on tumor cells and healthy tissue in pre-clinical settings, such as experiments done in cell cultures or mice. A majority of these radiation biology studies, however, have serious flaws in how their irradiation methodology is described, which makes them very difficult to replicate, according to a new finding from the University of Maryland School of Medicine (UMSOM).
