Here's a relevant excerpt

After administration of PLUVICTO
For 2 days after the administration of PLUVICTO, drink plenty of water in order to remain hydrated and to urinate as often as possible to eliminate the radiopharmaceutical product from your body.

Because this medicine is radioactive, you will have to follow the instructions described below to minimize radiation exposure to others unless otherwise instructed by your nuclear medicine doctor.

Contact with others in your household, children, and/or pregnant women
 limit close contact (less than 1 meter) with:
o others in your household for 2 days
o children and pregnant women for 7 days;
 sleep in a separate bedroom from:
o others in your household for 3 days
o children for 7 days
o pregnant women for 15 days;
 avoid sexual activity for 7 days;
 use effective birth control throughout treatment with PLUVICTO and for 14 weeks after your last dose.

Use of toilets
Take special precautions to avoid contamination during the 2 days after treatment.
 You must always sit when using the toilet.
 It is essential that you use toilet paper every time you use the toilet.
 Always wash your hands well after using the toilet.
 Flush all wipes and/or toilet paper down the toilet immediately after use.
 Flush any tissues or any other items that contain bodily waste, such as blood, urine and feces
down the toilet. Items that cannot be flushed down the toilet, such as bandages, must be placed in separate plastic waste disposal bags (according to “Waste disposal recommendations” below).

Showering and laundry
Take a shower every day for at least the first 7 days after treatment. Wash your underwear, pajamas, sheets and any clothes that contain sweat, blood or urine separately from the laundry of others in your household, using a standard washing cycle. You do not need to use bleach and do not need extra rinses.

Waste disposal recommendations
All items to be thrown away should be discarded in a separate plastic waste disposal bag to be used only for this purpose. Keep the plastic waste disposal bags separate from the other household waste and away from children and animals. A member of the hospital staff will tell you how and when to get rid of these waste disposal bags.
