Our planetó»s magnetic field is believed to be generated deep down in the Earthó»s core. And is created by the rotation of the Earth and Earth's core. It shields the Earth against harmful particles in space. The field is unstable and has changed often in the history of the Earth. The magnetic field creates magnetic poles that are near the geographical poles. A compass uses the geomagnetic field to find directions. Many migratory animals also use the field when they travel long distances each spring and fall. The magnetic poles will trade places during a magnetic reversal. | 0.23247 |

They told the men they were simply receiving free medical care. They never told the men that they had the dis- ease, nor were the men treated for the disease when a cure was discovered in the 1940s. Instead, the study continued for another 25 years. It came to an end only when a whistleblower made it a front- page story around the nation. | 0.281158 |

Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or 'decays' into an atom with a mass number that is reduced by four and an atomic number that is reduced by two. Alpha decay only occurs in very heavy elements such as uranium, thorium and radium. The nuclei of these atoms are very äóìneutron richó (i.e. have a lot more neutrons in their nucleus than they do protons) which makes emission of the alpha particle possible. After an atom ejects an alpha particle, a new parent atom is formed which has two less neutrons and two less protons. Thus, when Radium-226 decays by alpha emission, Radon-222 is created. | 0.221723 |
