Like you, I was admitted to the Pluvicto plan wthout having chemo first. Same reasons you expressed.
I had my second injection last Thursday, 09 May. I brought my geiger counter along and had the Physicist check it out. At his suggestion, I also measured the radiation of the injection syringe - at the tip, it measured about 150 mR/h and along the sides (it is inside a water-filled cylinder) it measured about 50 mR/h. I thought you might find that interesting.
