Japan may have to dump radioactive water into the sea, minister says

[Eko]

19. What toxins are you talking about that have a half life of forever?

Bear in mind a half life is
:in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive material to decrease by one-half. https://www.britannica.com/science/half-life-radioactivity
or
In science, a half-life (also, as a noun, spelled half life ) is the amount of time it takes for half of a substance or entity to undergo some specified process. For example, the half-life of a radioactive substance is the amount of time it takes for half of its atoms to decay, and the half-life of a drug is the amount of time it takes before half of the active elements are either eliminated or broken down by the body. Depending on the particular substance involved, a half-life may be significantly shorter or longer than half of the substance's full period of activity. https://whatis.techtarget.com/definition/half-life

We had this conversation before with something you picked and I showed you where the half life of that toxin was far less than radioactive elements, but you might have figured something else out so I am asking.
