ERS – Epsilon Radioactive Sources

I-125 Tumor Localization
Seed Source

I-125 Tumor Localization Seed Source is a pre-sterilized 18G stainless steel needle containing low activity I-125 iodine seed.
The I-125 source consists of a laser-welded titanium capsule containing iodine-125 adsorbed on a silver rod that acts as an x-ray detectable marker.

PET/CT, PET/MR
& SPECT Sources

Ge-68 line sources are double layered tubes and made of high quality stainless steel. Each line source is sealed on its ends by the process of precise argon welding. Thanks to the argon welding process, the possibility of activity leakage is eliminated, ensuring safe use of line sources.

DOSE CALIBRATOR
SOURCES

ERS dose calibrator reference sources are calibrated by direct comparison of standardized solutions traceable to the National Institute of Standards and Technology (NIST), in an identical geometry, using a pressurized ion chamber with ±%5 accuracy. Dose Calibrator sources are manufactured by adding 20 ml activity of epoxy composition in 30 ml volumed of polyethelen vial. Each dose calibrator source has its own colored-coded epoxy. Cobalt-57,
