Doha city centre sits 204.0 km from Ras Tanura, Saudi Arabia, the most plausible strategic target in the area (high targeting confidence). Modelled strike: 300 kt surface burst.
Estimated survival chance at city centre: 99%
What a strike on Ras Tanura, Saudi Arabia would mean
A 300 kt detonation produces a fireball 743 m across in radius. Reinforced concrete fails out to 1.8 km (20 psi). Most residential buildings collapse within 3.7 km (5 psi), and windows shatter dangerously out to 8.3 km (1 psi). Anyone in line of sight within 6.9 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 86 km east of ground zero. Doha city centre lies outside the projected corridor under these wind assumptions.

| Target | Type | Distance | Assumed yield | Confidence |
|---|---|---|---|---|
| Ras Tanura, Saudi Arabia | energy | 204 km | 300 kt | high |
| Dubai Intl | airport | 386 km | 150 kt | low |
| Riyadh | government | 493 km | 150 kt | medium |
| Natanz enrichment, Iran | energy | 938 km | 150 kt | high |
| Arak IR-40, Iran | energy | 1011 km | 150 kt | medium |
Key blast radii (300 kt surface burst)
| Effect | Radius | What happens |
|---|---|---|
| Fireball | 743 m | Complete vaporisation |
| 20 psi blast | 1.8 km | Hardened structures destroyed, ~100% fatalities |
| 5 psi blast | 3.7 km | Most buildings collapse, widespread fatalities |
| 3rd-degree burns | 6.9 km | Full-thickness burns to exposed skin |
| 500 rem radiation | 2.4 km | Lethal dose without medical care |
| 1 psi blast | 8.3 km | Window breakage, light damage, glass injuries |
How Doha can prepare
With a population density of 900 people/km², Doha'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.
