skuaThere is a high priority nuclear target about 20 km away. Prevailing winds have Perth WA downwind of it frequently.
We don't get iodine tablets. Or anything really about the danger.
It's kids who need the iodine the most to reduce the amount of radioactive iodine isotopes that their growing bodies will incorporate if exposed.
My bet is that the expiry date on those tablets would, if there is nuclear fallout present, be better completely ignored.
