The Geiger counter in the video is set to measure mR/hour (millirads/hour). Multiply the reading by 10 to get μSv/hr (microsieverts/hour). The readings in the video peak out at .320 mR/hour, or 3.2 μSv/hr. For perspective, only one Geiger counter in the collection of meters from Live Streaming Radiation Meters gets to whole numbers typically. This is the GM-fukushima meter situated in an outdoor cafe in Iitate Village, Fukushima Prefecture, Japan which is the closest meter in this collection to the Fukushima I nuclear power plant.

We got stuck next to this truck during the 7pm July 1st holiday traffic on North bound I-270, after seeing the Radioactive warning placards we pulled out the Geiger Counter and Camera. Lesson learned, AVOID RADIOACTIVE TRUCKS!
The Geiger counter samples over a 30 second moving average, updated every 3 seconds. Notice how the reading on the Geiger Counter keeps moving upwards after we pass the truck; had we stayed next to the radioactive truck the readings would have went even higher.
Pray for the truck driver; the source of gamma rays appeared to be located almost directly behind the driver. One would think that these things would be much more heavily shielded, located further away from the driver, and that such materials would be transported when other people are not on the road.
The truck exited I-270 at Lilac Ave.
