A 1950's civil defense film regarding radioactive fallout from nuclear blasts. In an ironic twist of fate, the simulation of a blast shown in this video takes place in St. Louis Missouri (my home town).
This films information on small particulate matter still applies today in regards to blasts from Nuclear reactors such as Fukushima.
Long term small particle radioactive fallout is the enemy in BOTH cases... nuclear blasts, or reactor meltdown hydrogen blasts which pulverize the radioactive elements (rods) into fine powder, ejecting the fine powder into atmospheric currents.
It takes several years for the particles in the jet stream to settle out across the globe. The half life of Cesium 137 is approximately 30 years.
The "fallout" from blasts, or large meltdown explosion events can take up to 10 years to fully dissipate. Meaning we need to watch precipitation, and the dust which builds up over time (as explained in this civil defense video).
I originally uploaded this the day Fukushima blew up in 2011, however upon my THIRD channel shutdown, I lost all videos prior to September 2011.
Thus the reupload here.

Here is the ORIGINAL list of Radiation links we assembled in the days following the Fukushima blast (and subsequent meltdown)... several links are not working -- but if you're really bored you can look up in the waybackmachine to see the information as it existed.
