Lop Nur nuclear blast radius
Last updated
Lop Nur was China’s nuclear test ground. This page uses a 21 kt analog for the early test class, not a full list of Chinese yields.

Educational estimate only. Blast and heat rings use simplified yield scaling. They ignore terrain, weather, shielding, and weapon design. Casualty counts use WorldPop 2020 residents on an approximately 1 km grid and ignore time of day, commuting, shelter, and evacuation. This is not a targeting or civil-defense tool. About the model.
| Effect | Ground range | What the model means |
|---|---|---|
| Fireball | 304 m (998 ft) | Maximum luminous radius |
| 20 psi | 938 m (3,078 ft) | Heavy destruction |
| 5 psi | 2.0 km (1.3 mi) | Most buildings collapse |
| Thermal | 2.3 km (1.4 mi) | 3rd-degree burns |
| 1 psi | 4.7 km (2.9 mi) | Windows shatter |

What the rings cover
Rings sit on desert basin around the test ground. 1 psi does not cover a coastal megacity. Casualty estimates stay low because the grid is empty, not because the yield is harmless.
China’s first test in 1964 was in the 20 kt class. Fat Man is the named yield this globe already has at that scale. Later tests here included thermonuclear shots; use Castle Bravo or Tsar Bomba on this pin in the simulator if you want megaton rings.
The desert siting is the same logic as Nevada and Semipalatinsk: keep the WorldPop grid empty. That does not erase later environmental and health debates around the range.
This is an educational pin, not a targeting page for any city in Xinjiang.
