Hello Ron,
Welcome to the club no-one wants to join!
I had radiotherapy 3 years ago: 37 sessions over 7.5 weeks. It was no real problem, and the staff at the radiotherapy department were very supportive and helpful. I had to drive 20 miles every weekday, but I found it no problem: that said, I know other folks did have have hospital transport arranged for them.
As to the side effects, in my case I did have slight bowel and bladder problems, but nothing I could not cope with.
If you have some time, I suggest you read the long thread on this site called "radiotherapy underway", where a number of us discussed out experiences. Also, if you don't have it already, I suggest you order the Prostate Cancer UK "Toolkit" of the main site: it is very helpful and covers everything in very clear language.
All the best,
Peter
