In the period 2019 to 2024, two new buildings have been built at Radiumhospitalet - a new clinic building and a proton building. The clinic building contains many of the same activities that take place in the hospital. The proton therapy building houses the highly advanced equipment required to be able to offer proton therapy, an offer patients previously had to go abroad to receive. The building will also contain other activities related to radiation therapy at Radiumhospitalet. Helse Sør-East RHF is the client and owner of the project.
