WEEK 3 SCI

• In the electromagnetic spectrum, as the frequency increases in size, its wavelength decreases.
• Radio wave has the widest wavelength range
• Gamma ray has the highest frequency in the electromagnetic spectrum
• a form of energy that acts by removing electrons from atoms and molecules of materials

  Ionizing radiation
• is a type of low-energy radiation that does not have enough energy to remove an electron from an atom or molecule

  Non-ionizing
• Ionizing radiation emits

  High-energy photons and particles
• Non-ionizing radiation emits

  photons with low energy levels
• 1 becquerel is equal to 1 decay per second
• one sievert is equivalent to 100 rem
• 1 rad = 0.01 Gy
• one curie is 37 billion Bq
• 100 rem = 1 Sv
• 1 Gy = 100 rad
• Pioneered the research on radioactivity and the discovery of elements polonium and radium
