I just wouldn't go end of story, Bad enough natural radiation levels on the granite and schist in Philadelphia, Cornwall and Scotland.
You might regret it when it catches up with you.

The dirty detonation puts the bomb so close to the ground level that the bad stuff is forced into the top layer of soil in high densities and spread locally. One of the worst was the 'Baker shot' in a lagoon, where the relatively small fission bomb not only radiated the seawater but also dredged up and radiated the seafloor spraying it all over the ships being used for the test. The radiation was far far higher because of this, and meant many test results couldn't be collected as it was way too dangerous to send men in.
The largest ever bomb exploded by the Russians, the so called Tsar bomb, was very clean because so much of the bad stuff simply went upwards. It also demonstrated that huge fusion bombs are not as effective as smaller bombs because the vast majority of the energy released went out into space. Thats good news because simple physics limits the destruction capability of larger bombs. Which is why modern fusion bombs don't go beyond a few megatons.
Cesium 137 is 30 years apparently. Never heard of it.
Pu 239 has a 24,000 year half life.

@stickyfiddle, did you actually hold you Geiger counter up to the ground? What about your boots?
