Who say's you can't have a little fun with cancer? This morning I was injected with the radioactive isotope gallium. Then I went to work and started playing with our 'geiger' counter. It's from our haz mat trailer, for use in case Osama succeeds in exploding a dirty bomb in North Bay (or in case a truck carrying radioactive material crashes on the highway, a much more likely occurrence). The counter showed a background radiation of less than 10 microsieverts, but when you point it at me you get about 20 microsieverts. When the counter was placed on the right side of my neck (where my tumour is), it shot up to about 40 microsieverts. That shows that the gallium is doing it's job, going to the tumours so that they will show up on tomorrow's x-rays. Maybe tomorrow I'll run the counter over my whole body--anyplace the radiation levels rise above 20 microsieverts should indicate a tumour location. On the other hand, maybe I'll just wait for the oncologist to go over the x-rays with me!
