Open the CIPO recordAbstract From the Canadian patent
A method of transmutation treatment of radioactive waste Radioactive nuclides to be treated contained in the radioactive wastes are accelerated to an energy level corresponding to a compound nucleus resonance level. The accelerated nuclides are then smashed or bombarded into a thermal neutron field which is under a magnetic field to, cause the compound nucleus resonance reaction to occur thereby transforming the radioactive nuclides into those which are more stable or have shorter life.

Why it's free to use
- Filed June 27, 1991 and granted May 5, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 27, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 27, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
