To estimate radiation dose, the dicentric chromosome assay (DCA) is commonly used. This test involves analyzing blood samples for the presence of dicentric chromosomes, which are indicative of exposure to ionizing radiation. The number of dicentric chromosomes can provide an estimate of the radiation dose received by an individual. Other tests, like the gamma-H2AX assay, may also be utilized for similar purposes.
A complete blood count (CBC) with differential test can provide information on white blood cell counts, which can be used to estimate radiation dose in cases of acute radiation exposure. Specifically, lymphocyte depletion kinetics can be used to estimate radiation dose.

The dicentric chromosome assay is a blood test that can accurately estimate radiation dose. This test looks for changes in the structure of specific chromosomes that can occur after exposure to ionizing radiation, and the frequency of these changes can be used to estimate the amount of radiation received.
lymphocyte cytogenetics
The dicentric chromosome assay is a blood test that provides an accurate estimate of radiation dose. It detects and quantifies chromosome damage caused by radiation exposure and is used in cases of suspected or accidental radiation exposure.
The method used to estimate a radiation dose by measuring the biological response to an observed dose of ionizing radiation is called biodosimetry. This technique analyzes specific biological markers, such as chromosomal aberrations or gene expression levels, to assess the level of exposure to radiation and estimate the resulting dose received by an individual.
The method used is called biological dosimetry, where the biological response (such as chromosome aberrations or gene mutations) is measured to estimate the radiation dose absorbed by an individual. This can help assess radiation exposure in cases of accidental or intentional radiation incidents.

This is not a routine practice, but it is desirable when transfusing animmunocompromised patient, as the T-lymphocytes in the transfused blood may otherwise provoke a graft-versus-host reaction. Low-dose ionising radiation inactivates the T-lymphocytes without harming the other blood components. Radiation has also been proposed as a method of sterilising the blood units, but much higher doses, which are not necessarily well tolerated by the blood cells, are needed for this purpose.
