Demonstration example of a IsoSeed used in low dose brachytherapy cancer treatment


Sealed demonstration example of a IsoSeed I-125 prostate brachytherapy seed, with no radioactive nucletides, made by BEBIG GBmH, an Eckert & Ziegler company, Berlin, Germany, 2017-2019

As small as a grain of rice, this is the type of ‘seed’ that is used in a cancer treatment known as low dose brachytherapy. To treat prostate cancer, 80 to 120 seeds are placed in the body via needles while a person has a general anaesthetic. By placing radioactive material into the prostate, cancerous cells are targeted while minimising the impact to healthy tissue. Each seed emits radiation of a radioisotope known as iodine-125 for up to a year. Fully visible under imaging techniques such as X-ray and CT, the IsoSeed I-125 is part of the IsoCord® system.
