Two Nuclear isomers are already found, the lengthier-lived a single becoming 24mNa with a fifty percent-lifetime of around 20.2 milliseconds. Acute neutron radiation, as from the nuclear criticality accident, converts many of the stable 23Na in human blood to 24Na; the neutron radiation dosage of the target may be calculated https://www.tjcyindustrialchem.com/news/sodium-chlorite-uses-and-the-difference-from-chlorine.html
