17 Neutron therapy
This database contains 17 Research Reactors performing Boron Neutron Capture Therapy distributed over 13 Member States.
Note that this view includes Reactors of the following status:

One of the neutron beam applications, less frequently promoted and known is neutron medical treatment or neutron therapy. The property of neutrons that differentiates this therapy from more conventional radiation therapy techniques like high energy X ray, electron or high energy proton treatment is their ability to damages cells using so called high linear energy transfer (LET). This is achieved by creation of secondary recoil protons and alpha particles, which distinguish two branches of neutron therapy, fast neutron therapy (FNT) and boron neutron capture therapy (BNCT), respectively.

FNT has been administered to about 30 000 patients worldwide, and 5 facilities continue to operate (4 accelerator based and 1 reactor based). With curative intention, presently FNT is used to treat prostate and lung cancer, adenoid-cystic carcinoma of head and neck, especially of the major salivary gland tumours, breast and in some cases also thyroid cancers.

The total number of patients treated by the BNCT remains below 1000 with three-fourths of all patients administered in 3 research reactors, namely FiR-1 in Finland and KUR & JRR4 in Japan. Although clinical results indicate significantly increased survival times, the outcome has been palliative only.
