“Bug Man” Testing For Radiation at the Hanford Plutonium Plant — 1956

Take a look at what the fashionable radiation detector was wearing in 1956 — it’s like something you’d see in a low-budget sci-fi movie: an ant-man in a jumpsuit, with antennae and a throat microphone. I’m not sure *I’d* feel confident wearing this in a “hot zone,” but it was apparently deemed safe by the Hanford plutonium plant (aka “the Hanford Site”) in Richland, Washington. Check it out.

The Tree Wireless — 1919

Using living trees as antennas was an important element of inventor Maj.-Gen George O. Squier’s system of telephony, which was developed for use during WWI as a way to intercept enemy messages which had been electrically transmitted, as well as to receive and transmit messages from just anywhere with a living tree nearby. More about Squier’s odd-sounding “tree wireless” inside.
