Recent studies on radium, polonium, and uranium proved foundational to the study of Pu toxicity. For example, polonium (another alpha emitter) research indicated that test sample contamination was a major concern, which is why a cleanroom had to be established at Los Alamos in February 1945 in the Medical Labs Building.

However, on November 6, despite Silkwood's prior decontamination and self-inspection, a detection on her part the next day yielded more signs of alpha activity on her hands, while health physics staff at the plant subsequently detected further alpha activity on her right forearm, neck and face.
“A moment on the lips, a half life on the hips.” Did a Tri-Cities scientist eat radioactive uranium in the ‘80s to prove that it is harmless?. Maybe, says a recent new fact check by Snopes.com.
Gilbert cloud chamber, assembled An alternative view of kit contents. The lab contained a cloud chamber allowing the viewer to watch alpha particles traveling at 12,000 miles per second (19,000,000 m/s), a spinthariscope showing the results of radioactive disintegration on a fluorescent screen, and an electroscope measuring the radioactivity of different substances in the set.
When asked if he would eat a cookie off a plate made of uranium glass, Dr. Frame answered "I have," and reminisced about a dinner party he went to were the entire meal was served on the stuff.
