After acute irradiation, a laboratory examination, including OAK, a biochemical blood test, a general urine test, is performed. Determine the blood group, compatibility and HLA antigens in case of blood transfusion or, if necessary, stem cell transplantation. Lymphocyte counts are performed 24, 48 and 72 hours after irradiation to assess the initial dose of radiation and the prognosis. A clinical blood test is repeated weekly. This is necessary to control the activity of the bone marrow and, if necessary, depending on the clinical course.

Leather |
Local erythema with intense burning or stinging, xerosis, keratosis, telangiectasia, vesicles, hair loss (within 5-21 days after irradiation). Dose> 5 Gy: moist gangrene, ulcer formation. Long-term effects: progressive fibrosis, squamous cell carcinoma |

* Irradiation of the whole body (approximate dose).
Pollution. With radionuclide exposure, the whole body is examined with a Geiger counter to detect external contamination. To detect internal contamination in the nostrils, ears, mouth and wounds, they are wiped with moist tampons, which are then tested with a counter. Urine, feces and vomit should also be checked for radioactivity.
