This TM design and position of the FF catheters enabled the Ir-192 HDR source to travel in close proximity to the cutaneous tissue to be treated.
The device apparently contained up to 10 grams (0.35 ounces) of Ir-192 "capsules", a radioactive isotope of iridium also used to treat cancer, a senior environment ministry official based in Basra confirmed.
"The material is classed as a Category 2 radioactive source by the IAEA, meaning that if not managed properly it could cause permanent injury to a person in close proximity to it for minutes or hours, and could be fatal to someone exposed for a period of hours to days," reports Reuters." Large quantities of Ir-192 have gone missing before in the United States, Britain and other countries, stoking fears among security officials that it could be used to make a dirty bomb." The article explains that a dirty bomb causes contamination rather than a nuclear explosion.

Significant isotopes in the brachytherapy market are cesium-131(Cs-131), iodine-125 (I-125), palladium-103 (Pd-103), and iridium-192 (Ir-192).
Radiographic inspection was used to verify the quality of weld and each repair (the source that was used is iridium-192 (Ir-192).
The third patient underwent three excisions within a span of five years, followed by local recurrence 5 years after last resection, and was managed with excision and brachytherapy with RT delivered five days postoperatively with low-dose rate Ir-192 brachytherapy to a dose of 60 Gy prescribed to 5 mm from the plane of the implant.
The material in the device, Iridium (Ir-192), is used for industrial radiography to help take pictures of metal weldings.
The device is used for industrial radiography and contains Iridium Ir-192. It was reported missing on October 25 to the Federal Authority of Nuclear Regulation.
