CIELO starts with a pilot launched by the OECD- NEA addressing a small number of high priority nuclides: H-1, O-16, Fe-56, U- 235, U-238,
Pu-239.
Experiments with rotating collimators cutting out pencil of alpha-particles at radioactive decay of
Pu-239 evidence sharp anisotropy of space.

According to Cosmos magazine: "Unlike U-235 and
Pu-239, no matter how much thorium you pack together, it will not start splitting atoms and blow up.
The type of plutonium in the bottle - known as
Pu-239 - is a so-called alpha emitter.
Mixtures with considerably less
Pu-239 than weapons-grade can in principle be made into a weapon, but they generate much radiation and heat, making weapons harder to build reliably.
Due to the advanced types of reactors proposed for building under this program, the overall amount of fuel available for consumption actually increases with each cyclical iteration, due to the transmutation of U-238 into burnable
Pu-239 in the reactor core (DOE, 2007.
Thus Ken Kalfus writes a terrific, bleakly beautiful first novel (following 1998's Thirst and 1999's
Pu-239, both collections, both great) that will effectively end up choir-preaching to the majority of its audience and go ignored by those most in need of its message.
Of the 175 cases of nuclear materials trafficking reported by the International Atomic Energy Agency (IAEA) between 1993 and 2001, only 17 involved U-238 or
Pu-239.
How much longer before we hear that
Pu-239 decays in 1,000 years?
8) provides a high fissile material production rate, which converts fertile U-238 to fissile
Pu-239.
In all, there were under 10 grammes of
Pu-239 with a purity of 99.
