  78. Three Principles of Radiation Protection:
    • Time: keep exposure to a minimum
    •          X-rays (photons) travel at the speed of light
    •          Human senses can not detect radiation

    Distance: inverse square law - the intensity of radiation is inversely proportional to the square of the distance.
