What is "radiumhemmet"

Radiumhemmet is a non-surgical cancer treatment and radiotherapy research institution in Solna, Sweden. Since 1938, it has been a division of what is now the Karolinska University Hospital. It was founded in 1910 in central Stockholm as the first oncological clinic in Sweden, succeeding a radium research and treatment institution at the Serafimerlasarett founded in 1906, and played a major role in the development of radiotherapy, especially in gynaecological cancers.
