As a result of the mishap radioactive particles escaped from the isotope handling cell and contaminated the laboratory, which was involved in producing radioactive sources containing iridium-192
Since April 1998, the firm has been marketing cobalt-60, iridium-192
, strontium-89, barium-133, and nickel-63.
These efforts have provided isotopes like Cobalt-60 for treatment of inoperable vascular deformities and brain tumors, and Iridium-192
for radiography research, along with other materials.
The study covers Iridium-192
, Selenium-75 and Cobalt-60 sources.
The cargo, which was sent by the Swedish high-tech company Studsvik AB to a US company that packages radiation sources for industrial use, contained pellets of the radioactive material Iridium-192
Afterward, they irradiated one of those two segments in each animal with iridium-192
, a gamma-ray-emitting isotope.
Best Medical currently manufactures Iridium-192
sources for cardiology applications for Cordis Corporation, a Johnson & Johnson company.
