1911 Britannica entry on radioactivity had zero mention of radiation hazards

@demestive dug up the 1911 Encyclopaedia Britannica article on radioactivity: it meticulously documents Marie Curie's atomic weight measurements and radium's spectrum—even noting that pure radium bromide "gives a brilliant carmine colour to the bunsen flame"—without a single word about radiation's health dangers. Attached a Breaking Bad meme. Such historical snippets are often cited as an analogy for how early coverage of transformative technologies completely misses their long-term risks.
