Characteristics

  • Measurement results are accurate.

    The FGD-650 glass dosimeter
    measuring system uses ultraviolet
    rays from the laser to repeatedly
    excite the glass element in a
    short time.
    Therefore, it can be measured
    multiple times with the average
    value being adopted as the measured value.

  • Fading (latent image regression) is small.

    The glass element, the
    manufacturing material of the
    dosimeter, has low sensitivity
    dispersion.
    Therefore, it is very stable,
    with environmental changes
    having very little influence on it.

  • It can be re-measured.

    Glass elements do not generate
    fluorescenc by heating like TLD.
    However, they do generate
    fluorescence when they are
    stimulated by ultraviolet rays
    and do not disappear.

  • Fast measurement time.

    The measurement speed is at
    least 2 times faster than
    TLD (thermal fluorescence
    dosimeter) by measuring the
    radio photoluminescence
    generated from the device
    in a short time.

    TLS-1000

  • Measuring equipment (TLS-1000)

  • ㅤ

*Passive neutron dosimetry conforming to ISO-21909 standard

  • Neutron measurement
    that is not affected
    by other radiation.

    Insensitive to X3, µ, β rays – The
    neutrons can be selectively
    measured even if they are in
    a mixed field of neutrons
    and X3, µ rays.

  • Fading (latent image regression) is small.

    For the chemical treatment of drops
    that are formed by neutrons,
    since latent image regression
    due to temperature and humidity
    is small, the required measurement
    accuracy can be maintained for
    a long period of time.

  • High sensitivity to
    neutrons of various
    energies.

    The combination of two filters in
    a transparent case Measures
    makes continuous neutron
    measurement from 0.025 eV
    to 15 MeV possible.
    Measures 144 keV energy,
    Bare2s2Cf, 241Am-Be neutron
    sources,etc., which are difficult
    to measure in existing
    TLD and OSLN.

  • Short measurement time.

    TLS-1000 can measure continuously
    by mounting 100 CR-39 elements.
    The time it takes to measure,
    including thermal neutrons and
    fast neutrons, is as short as
    40 seconds per unit.
