Radiosensitivity is the relative susceptibility of cells, tissues, organs, organisms, or other substances to the injurious action of radiation
In general, it has been found that cell radiosensitivity is directly proportional to the rate of cell division and inversely proportional to the degree of cell differentiation
The most radio-sensitive cells:
High division rate
High metabolic rate
Non-specialized type
Well nourished
Casarett classification:
Group I
Group II
Group III
Group IV
Michalowski classification (PMID: 7127027):
H-type (hierarchical): like hemopoietic tissues
