finding it hard to find beryllium foil without buying it from usa or israel, sworn enemies.
what other household items could work as a neutron target, multiplying if possible?
how about lithium from batteries? even maybe wrapping a dead lipo cell around an alpha/gamma source?
i read polythene makes a good moderator to slow down neutrons, so maybe source wrapped in alkaline metal, wrapped in yellowcake, wrapped in polythene greenhouse sheeting, then placed in the centre of a roll of roofing lead.
aim is to produce some spicy isotopes (spicytopes?) that work as a better gamma source than what i could make from my ore samples, and make a diy weld inspection camera.
companies wont sell cobalt cores to cunts like me.
inb4 whiny npc cunts tell me why i shouldnt do this etc
