OK, so we know it’s extremely unlikely that it will ever happen, but have you ever wondered what would happen if a nuclear bomb, like that supposedly tested by North Korea, hit Peterborough.
Well, now there’s a website to simulate just that!
You can run a simulation as to the impact a 10 kiloton hydrogen bomb, the one apparently tested by North Korea, or take a look at history and test the impact the Hiroshima or Nagasaki.
So, what does the simulation show would be the impact on Peterborough?
If, in the unlikely event the bomb was dropped in the city/town centre, the radius of the nuclear fireball would reach a diameter of 200 kilometres causing fatalities, taking out the city and many of the city’s landmarks including Peterborough Cathedral.
The air blast radius would reach up to 0.69 kilometres stretching out towards the ABAX Stadium in London Road. The pressure of the blast in this area would cause most buildings to collapse and widespread fatalities.
Radiation would reach almost 1.25 kilometres and without medical treatment, there can be would be between 50 per cent and 90 per cent mortality from acute effects alone.
Dying would take between several hours and several weeks. Depending on wind direction, people more than 1.41 kilometres away would suffer third degree burns.
Depending on wind direction, areas as far away as Spalding and Boston would also be affected along with the Lincolnshire Wolds.
Graph colour code:
Yellow - Fireball radius: 200 m (0.12 km²)
Maximum size of the nuclear fireball; relevance to lived effects depends on height of detonation. If it touches the ground, the amount of radioactive fallout is significantly increased.
Red - Air blast radius (20 psi): 470 m (0.69 km²)
At 20 psi overpressure, heavily built concrete buildings are severely damaged or demolished; fatalities approach 100%.
Grey - Air blast radius (5 psi): 0.99 km (3.06 km²)
At 5 psi overpressure, most residential buildings collapse, injuries are universal, fatalities are widespread.
Green - Radiation radius (500 rem): 1.25 km (4.91 km²)
500 rem radiation dose; without medical treatment, there can be expected between 50% and 90% mortality from acute effects alone. Dying takes between several hours and several weeks.
Orange - Thermal radiation radius (3rd degree burns): 1.41 km (6.22 km²)
Third degree burns extend throughout the layers of skin, and are often painless because they destroy the pain nerves. They can cause severe scarring or disablement, and can require amputation. 100% probability for 3rd degree burns at this yield is 8.4 cal/cm2.
