The following instrument types are the most commonly used as hand-held survey meters. The primary practical applications are listed. Used for alpha, beta and neutron measurement Used for alpha, beta and gamma measurement Used for gamma and X-ray measurement The instruments are designed to be hand-held, are battery powered and of low mass to allow easy manipulation. Other features include an easily readable display, in counts or radiation dose units, and an audible indication of the count rate. This is usually the “click” associated with the Geiger type instrument, and can also be an alarm warning sound when a rate of radiation counts or dose has been exceeded.
