CBC : Nuclear Cannons

Added

• Radiation-Safe Canister — a non-stackable portable lead container. Right-click opens a 3×3 (nine-slot) screen; radioactive items inside are fully shielded and add nothing to carried dose, making it the practical way to haul fission cores, enriched dust or uranium blocks. Contents persist on the item, and canisters cannot be placed inside canisters. Recipe: 6 lead ingots, 1 steel plate and 1 steel ingot.

Changed

• Nuclear contamination clouds are far more lethal in the first minute. Fission cloud peak 15 → 200 rad/s, fusion 30 → 400 rad/s (hundreds of rad/s inside a fresh mushroom cloud). Diffusion and the ~120 s half-life still clear them quickly, so the acute danger is concentrated at detonation rather than lingering for an hour.
• Flash shielding strengthened. Lead attenuation 0.20 → 2.0 per block — one lead block now stops ~99% of the instantaneous burst; reinforced concrete 0.06 → 0.7 (one block ~80%, two ~96%, three ~99%).
• Full anti-radiation suit reduction 85% → 90% (the four pieces still total 70%; the full-set bonus rises 15% → 20%).
• RadAway strengthened. Instant purge 150 → 200 rad; the follow-up effect goes from 30 s at 4 rad/s to 35 s at 4 rad/s.
• Fallout weakened per piece, 1.0 → 0.5 rad/s (item and block). It still applies the surface-contamination effect on contact.
