N2 - 31P can be activated to β-emitter 32P by neutron bombardment. Chemically durable glasses containing a large amount of phosphorus is believed to be useful for in situ irradiation of cancers. A silica glass was implanted with phosphorus ion, heat-treated at 400°C in H2 to make phosphorus colloids grow, then heat-treated at 900°C in O2 in order to encapsulate the colloids with thin SiO2P2O5 glass layer. Thus treated glass showed little dissolution even in hot water and is expected to be useful for radiotherapy.
