- Blast effects of nuclear bomb (this is for an 80 col. printout)
- All distances to effect in miles. Note: airburst distances in ( )
- Airburst for optimum damage for that effect, since the height of airburst
- changes these figures represent worst case. See example for fixed height
- results.

- (fixed height of burst at 3,800 ft to maximize 30 PSI effect)
- 1 MT 9 6.5 4 2.6 1.9 1.05
- (fixed height of burst at 8,500 ft to maximize 6 PSI effect)
- 1 MT 11 9 5 3.2 2 not at ground zero
- (fixed height of burst at 15,500 ft to maximize 1 PSI effect)
- 1 MT 13 10 4.8 1.7 not obtainable at ground zero
- Note 1MT yields a fireball of about 3,600 feet in radius with a maximum height
- for contaminating burst of 3,000 feet.

- British Home Office blast catgories are
-
- Class. Degree of house damage PSI range
- A Complete/Debris 11+
- B Heavy 6-11
- C Heavy to light 1.5-6
- D Light,glass & tile 0.75-1.5
-
- Examples of damage (Clayton, from Gladstone)
- 0.5 psi Private airplanes damaged but flyable, windows have light damage
- 1.0 psi Windows heavily damaged, wood frame houses lightly damaged
- 2 psi Human body thrown hard enough to cause incapcitating injuries
- 3 psi Human body thrown hard enough to cause 1% fatalities
- 5 psi Wood frame house collapse, 1% of eardrums rupture (elderly)
- 6 psi Human body thrown hard enough to cause 99% fatalities
- 7 psi Reinforced concrete houses lightly damaged
- 15 psi Minor injury to lungs from overpressure (1 ATM)
- 25 psi Reinforced concrete houses collapse
-
- Note most in-site blast shelters are typically 1 or 3 ATM designs.
- 1 ATM equals 15 psi.
