Depleted uranium bullets were use as munitions during the Kuwait – Iraq war and the International
Atomic Energy Agency sampling expert’s team found fragments in the environment when the war
was over. Consequently, there is a possibility that members of the public, especially children,
collects DU fragments and use it, for example, to make a necklace. This paper estimates the beta
skin dose to a child that uses a necklace made with a depleted uranium bullet. The theoretical model
for dose estimation is based on Loevinguer’s equation with a correction factor adjusted for the
maximum beta energy in the range between 0.1 and 2.5 MeV calculated taking into account the
International Atomic Energy Agency expected doses rates in air at one meter distance of a point
source of 37 GBq, function of the maximum beta energy. The dose rate estimated by this work
due to the child use of a necklace with one depleted uranium bullet of 300 g was in good
agreement with other results founded in literature.
