This is just wrong - just because something is radioactive doesn't mean it is dangerous or will kill you. Learn some basic physical concepts behind alpha, beta and gamma radiation, about dose and dose equivalent and what radiation sickness really means. You all are narrating fear that was installed by MSM.
And you believe in everything the MSM writes? Weapon grade means only the concentration of Pu and the Isotope not the amount.
