«It was nowhere near as complex of a release as Chernobyl, which was everything from the
core of the reactor,» says Peter Caracappa, a radiation safety officer and clinical assistant professor of
nuclear engineering at Rensselaer Polytechnic Institute in Troy, N.Y. «This was a slow release,» he adds, and it was limited to a few radioactive materials, including iodine 131, which has a half - life of just eight days and therefore does not lead to long -
term contamination.
The size of the reactor's
nuclear core is a fraction of those of large conventional
nuclear power plants, with an attendant small radioactive source
term.
