Question: It's 2016, but for some reason, the Cold War never ended. You've been inspired by your (for some inexplicable reason) favorite movie, Indiana Jones 4, to start a new business: building refrigerators. However, the market is so saturated that in order to distinguish yourself with a nice marketing campaign, you decide to make them **NUKEPROOF!** 

The refrigerator should be:

1. Usable as a real refrigerator would be.
2. No bigger than standard double door refrigerator, so no room-sized walk-in refrigerator. Though, you *can* add some additional size for additional armor, for example, in **reasonable** margins, so nothing like 10 meters of iron from one side.
3. Protect one person from up to 1.2 megatonnes of a TNT nuke at a minimum distance of 2 km from the explosion.

How are you going to design it and what materials are you going to use?

Answer: 
Your customers will need to:
Put your fridge underground in the cellar;  

Reinforce the cellar walls to withstand the shockwave of the blast and the collapse of the house on top. 

Add shielding in 2 layers, preferably tungsten, 0.5" each layer, since lead is just messy, on the outer side of the body, and on the inside, just behind the fibreglass interior. Put the insulation in between the two layers of tungsten. The piping and wiring to the outside from the inner compartment should leave through the bottom of the fridge.  

Recommend buyers get **TWO** fridges, or one for every member of the family and a spare for actually keeping food in.
Add an asterisk to "Protect":

> 
> Protect\* one person from up to 1.2 megatonnes of a TNT nuke at a minimum distance of 2 km from the explosion.
> 
> 
> 

\* Protect: the explosion will not kill you and the nuke will leave no lasting ill effects. Protection may also apply to others near fridge.

Simply make a normal fridge with small extra box with a piece of string hanging out. "Nuke conversion"-kits also sold separately.

In the event of an imminent nearby nuclear explosion simply enter the fridge, pull the string and the 40 kg of TNT in the box will explode, preventing the nuclear blast from killing you.

Double your money back if the nuke kills you, upon personal application.
