Have been looking at how radiation is presented, and explained in recent centuries. What is ra-diation? How do we interact with “it.” And it with us. Also the types and spectrums of radiation. Came upon picture-book version for recent history, with nicely done primer images:
“A short lesson in how radiation enters the human body, compliments of the Atomic Testing Museum in Las Vegas, Nevada. These images are from a booklet on nuclear testing on Bikini Atoll…” Thanks to http://www.IodineHistory.blogspot.com for pulling together the images. http://iodinehistory.blogspot.com/2013/02/radiation-101.html
