It consists of a bun sometimes baked, sometimes fried, made from a sweet yeasted dough similar to that used for making doughnuts, split and then filled with raspberry or strawberry jam and cream, most often with a dusting of sugar on the top. The Kitchener bun resembles the Berliner, a pastry of German origin – although distinguished from it by an open face and the use
Commonly used gamma-emitting isotopes of normal non-radioactive cobalt and iridium metal in a nuclear reactor, creating radioactive nuclides of these elements which contain extra neutrons, compared to the original stable nuclides. In addition to their uses in radiography, both cobalt-60 (Co-60) and iridium-192 (Ir-192) are used in the radiotherapy of cancer. Cobalt-60 tends to be used in teletherapy units as a higher photon energy alternative to Cs-137, while iridium-192 tends to be used in a different mode of therapy, internal radiotherapy or brachytherapy. The iridium wires for brachytherapy are a palladium-coated iridium/palladium alloy wire made radioactive by neutron activation. This wire is then inserted
