• Low-energy sources for HDR brachytherapy
– electronic brachytherapy (eBT) can turn on/off
– similar dose distributions to HDR
125
I source
– independence from a radioactive materials license
– diminished shielding/licensing/security required
– potential to replace radionuclide-based brachytherapy
like linacs replaced
