Nuclear Impact Analysis · India

Is Bangalore safe from a nuclear strike?

We modelled the most plausible strategic targets around Bangalore and simulated blast, thermal, radiation and fallout effects against its 13,600,000 metro residents.

100/100
MINIMAL RISK

Bangalore city centre sits 533.9 km from Kudankulam Nuclear, India, the most plausible strategic target in the area (low targeting confidence). Modelled strike: 100 kt surface burst.

Estimated survival chance at city centre: 99%

What a strike on Kudankulam Nuclear, India would mean

A 100 kt detonation produces a fireball 479 m across in radius. Reinforced concrete fails out to 1.3 km (20 psi). Most residential buildings collapse within 2.6 km (5 psi), and windows shatter dangerously out to 5.8 km (1 psi). Anyone in line of sight within 4.4 km suffers third-degree burns from the thermal pulse.

Because military and hardened targets are typically attacked with surface bursts, fallout matters here: with prevailing winds the dangerous plume would stretch roughly 52 km east of ground zero. Bangalore city centre lies outside the projected corridor under these wind assumptions.

How Bangalore can prepare

With a population density of 4,400 people/km², Bangalore's outcome would hinge on the first hour. The guidance is identical everywhere: get inside, stay inside, stay tuned. A basement or the core of a large concrete building cuts fallout exposure by a factor of 10 or more, and radiation decays fast — dose rates fall ~90% within the first 7 hours and ~99% within two days.
