In a dental office, the person giving a dental x-ray examination leaves the room while the x-ray source is active. Dental office workers do not, however, take similar precautions against the bright lights of the exam room. Explain this difference.
a. Because x-ray photons carry much more energy than the photons of visible light, repeated exposure to x-rays can cause much more cumulative cell damage to the dental worker.
b. Because x-ray photons have a longer wavelength than the photons of visible light, repeated exposure to x-rays can cause much more cumulative cell damage to the dental worker.
c. Because x-ray photons have a lower frequency than the photons of visible light, repeated exposure to x-rays can cause much more cumulative cell damage to the dental worker.
d. Because x-ray photons are more massive than the photons of visible light, they penetrate more deeply into tissue, so repeated exposure to x-rays can cause much more cumulative cell damage to the dental worker.
