Most of it is fear mongering but you know bioaccumulation is a thing right? Water is a nice shield against radiation reaching you but if radioactive nucleai are in the water, it’s going to accumulate in animals that grow in that water and cause heavy metal poisoning, like Mercury.
Try to not be reactive. Take appropriate action whenever needed but choose to act after a delay so that you aren’t responding impulsively. In my experience 90% of conversations that were problematic could have been avoided if either party chose to walk away or take a break.
