More than half of material thefts reported to IAEA occurred during transport
The International Atomic Energy Agency has said that more than half of all thefts of nuclear and other radioactive material reported to the agency’s Incident and Trafficking Database (ITDB) since 1993 occurred during authorized transport, with the share rising to nearly 70 percent in the past decade. The ITDB covers incidents involving nuclear material, radioisotopes, and radioactively contaminated material.

A satellite carrying radioactive material in a near-Earth orbit has a finite probability of reentering before the radioactivity has decayed to a harmless level. If the reentry is unplanned, it is normally impossible to predict the impact point to a useful degree of accuracy. This paper deals with such cases. The probability distribution function for latitude of impact is derived for a general case. This function is then combined with an injury probability model and a population distribution model to compute probabilities of injury. The results are correlated as the dependence of probability of injury on latitude and orbital inclination angle. It is shown that probability of injury peaks for an orbital inclination of 30 to 60°.
