- For the public, neither military nor civilian use of depleted uranium should have exposures to above the normal background uranium levels. Individual exposure to DU is not needed. Exposure evaluation based on measurements of the environment may be needed for information and reassurance to the public.
- When a person is suspected of being exposed to high levels of DU, DU assessment is required. This is done with urine analysis as the urine provides useful data in the prognosis of the kidneys from DU or uranium. A proportion for DU and urine should be 235U/238U in ratio and gathered using mass spectrometry principles.
- Fecal measurement can also be used for assessment but fecal defecation of natural uranium from diet is 500 µg every day and may vary. This assessment should be considered very carefully.
- External radiation measurement in the chest and lungs need special facilities. This is done to ensure that the DU inside the lungs is 10 mg (excluding soluble compounds).
- To decrease the human absorption of uranium in the gastrointestinal tract or lungs has no specific means. After suffering from a bad internal contamination, the treatment consists of intravenous transfusion with isotonic 1.4 % sodium bicarbonate to get the excretion of uranium higher. The DU levels in humans should not reach an amount that justifies the intravenous treatment more than dialysis.
