The pioneers who explored the science of RADIOACTIVITY
Before he met Marie, Pierre Curie researched crystals and magnetism. He showed that a substance’s magnetic properties change at a certain temperature, a level now called the CURIE POINT. He joined Marie’s radioactive research a few years after they married.
Marie and Pierre Curie, and their daughter Irène, researched radiation, blazing trails in the fields of medicine and nuclear physics. By the way… My notebooks are o to radioactive. They’re and dangerous to touch ed are kept in lead-lin boxes, which trap the radiation.
Marie Curie Born in Poland, Marie Curie was taught physics and mathematics by her father. For further studies, she moved to Paris, France, where she met and married French physicist Pierre Curie. The Curies worked on RADIOACTIVITY, and in 1898, they discovered two radioactive elements – polonium and radium. For this work, they received the 1903 Nobel Prize in Physics.
What came after… In 1928, the GeiGer counter was invented by German physicist Hans Wilhelm Geiger to measure radiation. It produces a “click” when radioactivity is detected. 66
Food irradiation is the process of exposing food to safe levels of radiation to extend its shelf life. Depending on the dose, the radiation will kill some or all bacteria, moulds, and insects.
