Home-based nuclear fallout shelters combined everything that magazines needed in the 1960s to attract readers: fear, home remodeling, and the opportunity for producing great cutaways.
Just going into your basement during nuclear attack would decrease your chance of radioactive exposure to 10% of the exposure if you had stayed outside.
By undertaking some pretty major home remodels, all located in your basement and all eventually unused, you could shrink that statistic another ten-fold.

In 1961, LIFE extolled the benefits of building a basement bomb shelter out of pre-cast concrete blocks.
This cutaway drawing shows how the homeowner would have situated the shelter in a corner of the basement where it had no windows.
The article estimated materials cost not to exceed $200. It was estimated that radiation within the shelter would be about 1% of radiation outside.
As a final warning, the article mentioned that, should the nuclear warhead hit within 10-15 miles of you, the house might be blown down onto the shelter and catch fire.
