    Q1: What is a radiation detector?
    A1: Radiation Detector is an instrument used to detect or identify high-energy particles, such as those produced by nuclear decay, cosmic radiation, or reactions in a particle accelerator.

    Q2: How does a personal radiation detector work?
    A2: Personal radiation detectors are very sensitive, designed to detect changes in the gamma radiation level slightly above the background with a fast response time. Most PRDs provide a digital display of the exposure rate and a visual, auditory, or vibratory alarm at preset thresholds.

    Q3: What should I look for in a radiation detector?
    A3: The selection considerations for radiation detectors include: Type(s) of radiation for which exposure is expected (alpha, beta, gamma, neutron, X-rays, etc.) Desired functions – is the use to measure total radiation dosage over time (as with a dosimeter), or is a more detailed measurement needed?

    Tips: What should be paid attention to when using a radiation detector?

    • During the use of the instrument, it is necessary to ensure that there is no obstruction between the detection port of the radiation detector and the radioactive source to be measured.
    • When using the radiation detector to measure the reflection source, the measurement window should not face the sun, otherwise the reading may be affected to a certain extent.
    • The probe should be installed in the mesh window on the back of the radiation detector, and the mesh window needs to be aligned with the object to be measured during the measurement.
    • When the mode switch is in mR/hr, μSV/hr or CPMCPS state, the reading displayed by the instrument will be displayed every three seconds, which may cause significant fluctuations in the displayed radiation level at low count rates.

    Portable and useful nuclear radiation meter
    I bought this personal nuclear radiation detector to detect the radiation of the electronics, it works well and it is small so I can easily fit it in a shirt pocket. It is worth the cost!
