    Study Notes

    Radiation

    • Ionizing radiation is capable of producing ions through interaction with matter.
    • Non-ionizing radiation does not have energies great enough to ionize matter.
    • Ionizing radiation is commonly found in nuclear operations or research companies and medical facilities.
    • Ionizing radiation is dangerous in high amounts and capable of producing ions through interaction with matter.

    Environmental Conditions

    • The term "environment" describes the all-encompassing condition associated with a given environment.
    • The term "exposure" describes the condition resulting from a single exposure.

    Noise and Hearing

    • The standard unit for measuring noise levels is decibel (dB).
    • The term "sound" describes the auditory sensation evoked by oscillations in pressure in a medium.
    • Conductive hearing loss restricts the transmission of sound to the cochlea or inner ear.
    • The most effective control measure for noise-induced hearing loss is using hearing protection devices.

    Thermal Stress

    • Heat stroke is the most serious heat-related illness.
    • The most effective control measure for thermal stress in hot environments is providing adequate hydration and rest.
    • The recommended strategy for reducing the risk of cold-related illnesses is using protective clothing and limiting exposure.

    Vibration

    • The primary health effect of whole body vibration is fatigue and discomfort.
    • The most effective strategy employers can use to reduce the risk of vibrations is implementing vibration-reducing measures and providing regular breaks.
    • Frostnip is the mildest type of cold-related injury.
    • Raynaud's phenomenon, also known as white fingers, is caused by exposure to cold temperatures and vibration.

    General Health

    • The primary cause of white fingers, also known as Raynaud's phenomenon, is exposure to cold temperatures and vibration.
    • The term "radiation" describes the emission of electromagnetic energy.
