Fauntleroy,
Not knowing what (Dart) was I went to Dattoli's site and at least was able to verify that it was a type of radiation; without a medical dictionary that was all I was able to discover. My degree in English 49 years ago didn't help a bit!
At 100 days or close to 3 months I think you are doing very well for a radiation guy with seeds. I did note that this Dr is very proud about
his business and is outspoken about
his opposition to surgery__maybe that was to be expected.
You'll be fine-All the best to you.
Bill
