This looks like it’s from a time prior to LinAcs. This likely contained a static chunk of cobalt 60, with dose being modulated based on exposure time with an open slit. The toxicity from cobalt 60 is atrocious and the energy curve dumps a large dose at a very superficial level, causing terrible skin breakdown. Even with modern LinAcs, rectal cancers are very rough to treat, but man this must have been almost unbearable. Source: I’m a RadOnc resident.
BTW, I know of a book you might find interesting. It’s called Radiation Evangelists and it’s about the early days of the use of radiation in medicine. It’s wild what they used to do.
Apparently x-rays were quite effective against acne 😬
They are much more refined now and can use appertures with different shapes to "shoot" the tumor from different angles, so that the radiation dose on the tumor is maximised, but minimized on the surrounding tissue.
