How hematopoietic stem cells respond to irradiation: similarities and differences between low versus high doses of ionizing radiation

Scientific understanding of radiation effects is a constantly evolving field. However, it can be sometimes tricky to define doses of radiation, given the different units in which it can be expressed. The “absorbed dose” is expressed in Gray (Gy) while the “equivalent dose” and the “efficient dose” are expressed in Sievert (Sv). While they both correspond to the same units in the International Units System (J/kg), the relationship between these parameters implies several multiplicative fa ctors taking into account the type of radiation, the organ sensitivity or the species [1].
