Through  his  use  of  the  scientific  method,  Röntgen  found that x-rays:
1.Are highly penetrating, invisible rays that are a form of electromagnetic radiation.
2.Are electrically neutral and,  therefore,  not affected by either electric or magnetic fields.
3.Can be produced over a wide variety of energies and wavelengths (polyenergetic and heterogeneous).
4.Release very small amounts of heat upon passing through matter.
5.Travel in straight lines.
6.Travel  at  the  speed  of  light  
7.Can ionize matter.
8.Cause fluorescence (the emission of light) of certain crystals.
9.Cannot be focused by a lens.
10.Affect photographic film.
11.Produce chemical and biological changes in matter through ionization and excitation.
12.Produce secondary and scatter radiation.

When passing through normal matter, X-rays were observed to produce electrically charged particles along their path. The altered atoms or molecules comprising these charged particles were called ions. ]]> 2021-08-25 22:37:24 UTC https://padlet.com/lizaterron/ftn4ohmqpkgr3o64/wish/1696921115 Radiation Quantities lizaterron https://padlet.com/lizaterron/ftn4ohmqpkgr3o64/wish/1696947390 Exposure is the amount of ionization produced in air when ionizing radiation is present.
Absorbed dose is the amount of energy that is deposit in a material per unit mass of the material.
Effective dose is an attempt to provide a quantity that is a measure of general harm in humans. ]]> 2021-08-25 23:06:36 UTC https://padlet.com/lizaterron/ftn4ohmqpkgr3o64/wish/1696947390 lizaterron https://padlet.com/lizaterron/ftn4ohmqpkgr3o64/wish/1696970201  Radon gas is colorless, odorless, radioactive gas ]]> 2021-08-25 23:27:26 UTC https://padlet.com/lizaterron/ftn4ohmqpkgr3o64/wish/1696970201 ORP lizaterron https://padlet.com/lizaterron/ftn4ohmqpkgr3o64/wish/1696972138 Optimization for radiation.
