Nobel Prize-winning physicist Marie Curie did pioneering work on the properties of radiation. In the late nineteenth and early twentieth centuries, she and her husband did years of research with radioactive substances. By 1920, Curie was suffering the effects of exposure to radiation. She was losing her vision. Multiple operations were required to repair the damage to her eyes. She needed assistance getting around her own lab. Curie did not connect her medical problems with her experiments with radioactivity. She continued with her work and soon suffered other health problems.
Why is the time period important to the understanding of the passage?
Responses
In 1920, it was still not known that radioactive substances are toxic and this explains why Curie continued her experiments.
Pick the answer below.
In 1920, radioactivity was a novelty and Curie could not stop her work because of public demand for information about it.
Pick the answer below.
In 1920, the state of eye surgery was primitive and this is why Curie needed several operations rather than just one.
