After viewing them, I highly recommend for anyone to take a gander on over. The voice of the videos is alluring and the graphics are simple and creative.
For me, the video on Quantities and Units of radiation (below) was the best of the seven. Understanding units of radiation is always tricky for me and I’m sure others. There are Sieverts, there are Rems, there are Becquerels and so on. The video explains it all quite lucidly.
