It's the International Day of #MedicalPhysics. Today we commemorate the anniversary of the birth of Marie Curie in 1867. She pioneered 💡 research on #radioactivity ☢️ and discovered it destroys #cancer cells faster than healthy cells, paving the way for #radiotherapy. She won a Nobel Prize for #Physics in 1903 and a second Nobel Prize, this time in Chemistry, in 1911.
