1. It's R60. IR air to air missile.
2. It's either U235+U238 or depleted uranium (DU) which is mostly U238. Can't be both.
3. If there are traces of both U235 and U238, it's probably from old soviet optics (glass, ceramics) that can be found in R60s IR homing systems

Christmas, the ultimate 'gifting' season is almost upon us so why not consider searching out 'The Gilbert U238 Atomic Energy Laboratory' (1950's) for especially fickle children. Genuinely radioactive, it is believed to be the most dangerous toy in the world

there's essentially two ways you can make bomb-grade nuclear material:
1. centrifuge natural uranium, because 99%+ of the isotope mix is useless U238
2. put reactor grade fuel in reactor and run it in a very specific way for a short period of time

but, you can also use Plutonium!
but not all Plutonium is created equal!
if you run a fission reactor with low-enriched Uranium (LEU, ~5%) it means most of your fuel pellets are actually U238
they eat neutrons. and they become Plutonium isotopes
but not all Plutonium is created equal!

centrifuging uranium is literally just about getting slightly heavier U238 out and increasing concentration of U235, which is actually fissile. you need 80%+ of U235 to make a weapon. you get a weapon there without ever running it in a reactor, so it's more "stealthy" to try

Pu239 produced scales up nonlinearly with reactor thermal power rating. a 5 MWth research reactor is going to produce *grams per year* instead of kilograms needed for a weapons pit.
also they have less U238 for research reactor fuel! so you have even less to irradiate and transmute to Pu239!

La cámara de Wilson o cámara de niebla, es un dispositivo utilizado para observar la emisión de partículas de radiación ionizante, como este caso con un mineral de Uranio.
En la naturaleza, el 99% del U es de tipo U238, que al descomponerse en Th234 emite una partícula alfa.

Depleted uranium not enriched, just to be clear. Enriched uranium, which has a higher % of U235 compared to U238, is used in nuclear reactors. The leftover is depleted uranium which is radioactive but not fissile.

The real interesting part is the peak at 185 keV - that's a dead giveaway for U235! Which means my plate contains both U235 and U238, as it was made with natural uranium, and thus dates to the late 1930s.
Depleted uranium was used in the 50s, and that's just U238.
