Isotope contrast dye yes, she's done that a few times already.
For fun I'd turn off the room lights and say, "Are we glowing yet?" We have yet to determine if she needs Radioactive therapy. That would be following a few more Chemotherapy sessions and another CT scan to be done.
My kids and I decided to at least spend a good part of Mondays together and maybe tick off a "Bucket list item" if she could rally up enough energy and stamina to have a go at something fun and make our time count. After five sessions we can already see how this treatment is wearing her down.
