Come off it
The SS-20 had a yield of 450kt (3x 150kt MIRVs), and was a surgical strike weapon, so your claim that you were in danger of "getting irradiated by several hundred megatons" is somewhat overblown.

Depends if more than one missle were used...I lived in East Anglia remember
If memory serves, there were a lot of nice juicy targets there in 1984.

This is true, but you'd need 1,000 MIRVs to get to hundreds of megatons.

or "How I learned to stop worrying and love the bomb".
Whether it was SS-20s, SS-18s or whatever, the megatonnage would likely be a moot point. Artistic license overrules.
