Atomic Absorption Spectroscopy: Radiation and Light Sources01:13

Atomic Absorption Spectroscopy: Radiation and Light Sources

1.3K
Atomic absorption spectroscopy (AAS) relies on the Beer-Lambert law, which requires that the radiation source emits a narrow range of wavelengths to match the absorption characteristics of the analyte atom. The primary criteria for choosing an appropriate radiation source in AAS is to provide a precise and intense emission at specific wavelengths that will allow accurate detection of the analyte.
Two common narrow-range 'line' sources used in AAS are hollow-cathode lamps (HCLs) and...

    Summary

    Aircrew laser exposure at altitude is a distraction, not a threat to eye safety. Review of military patient encounters found no acute injuries, suggesting a policy change for USAF laser exposure guidelines.

    Area of Science:

    • Aviation Safety
    • Ophthalmology
    • Aerospace Medicine

    Background:

    • Laser devices are common but pose eye hazards, with documented injuries.
    • A misunderstanding exists regarding the risk of laser exposure to aircrew eyes.
    • This study aims to clarify the actual threat of laser exposure to aircrew.

    Purpose of the Study:

    • To raise awareness that aircrew laser exposure is a distraction, not a threat.
    • To propose a change to Air Force (USAF) policy on laser exposures.
    • To improve education for flight surgeons regarding laser incidents.

    Main Methods:

    • Reviewed electronic medical records (EMR) from a deployed clinic (July 2016-Jan 2017).
    • Analyzed patient encounters for eye-related laser exposure, injury, and flight duty status.

  • Included military aircrew (loadmasters, boom operators, pilots) without protective optics.

    • Main Results:

    • 21 encounters were reviewed; one patient had two separate instances.
    • 14 exposures involved green lasers, one was white, and six had unspecified colors.
    • No acute eye injuries were documented in any of the reviewed cases.

    Conclusions:

    • Patients were unnecessarily examined and grounded following laser exposure incidents.
    • Evidence suggests handheld laser exposure from the ground does not cause eye injury in flight.
    • Recommends treating laser incidents as distractions and revising USAF laser exposure policy.
