MSH: The ratio of radiation dosages required to produce identical change based on a formula comparing other types of radiation with that of gamma or roentgen rays.,CSP: ratio of radiation dosages required to produce identical change based on a formula comparing other types of radiation with that of gamma or roentgen rays.,NCI: A factor assigned to a type of ionizing radiation in converting absorbed dose measured in grays to a biologically equivalent dose measured in sieverts. In formula form, (equivalent dose) = (quality factor) x (absorbed dose). (Dr. Joseph A. Thie)
