He discovered that uranium minerals, even if wrapped in paper and stored in the dark, would produce dark images on photographic plates.
Antoine-Henri Becqueral
Showed that radioactive emissions were unaffected by temp, pressure, etc.
Discovered Polonium and radium.
Marie and Pierre Curie
3 common types of radiation are
alpha, beta, and gamma.
Properties of alpha radiation are
Helium (+ charge) emitted from unstable nuclei
Properties of beta radiation are
High speed electrons (- charge) emitted from unstable nuclei
Properties of gamma radiation are
High energy electromagnetic radiation of very short wavelength that usually accompanies other radioactive emission.
The induced conversation of an atom of one element to an atom of another element is called
nuclear transmutation
The splitting of a nucleus into 2 smaller nuclei with a release of energy is called
nuclear fission
nuclear fission is used in
nuclear power plants to generate electricity and the atomic .
Physicist who designed the first functional nuclear fission reactor
Enrico Fermi
Combining the nuclei of 2 atoms to form a more massive atom with the release of energy is called
nuclear fusion
nuclear fusion is used in
the hydrogen , and occurs naturally in the Sun.
2 things used to measure radiation are
geiger counter and dosimeter
Radiation can be used for
electricity generation(fission), fire alarms(radioactive nuclides), medicine(radioisotopes, radiation therapy, etc), and food perservation.
Half life is
the time it takes for half of a radioisotope (radioactive) to decay.
