IEC 60325 pdf download – Radiation protection instrumentation – Alpha, beta and alpha/beta (beta energy >60 keV) contamination meters and monitors
This International Standard is applicable to radiation meters and monitors designed for thedirect measurement or the direct detection of surface contamination by alpha and/or betaradiation emitting nuclides and which comprise at least:
a detection assembly (comprising y counter tube，scintillation detector or semiconductordetector,etc), which may be connected either rigidly or by means of a flexible cable orincorporated into a single assembly.
a measurement assembly.
Some meters and monitors consist of detection assemblies and measurement assemblieswhere it is possible to separate the detector assembly and use alternative detectionassemblies. Conformity with the standard can either be achieved by:
All combinations of the detection assembly and the measurement assembly conforming to therequirements of this standard.
or
The detection assembly and the measurement assembly separately conforming to therelevant parts of this standard in isolation.
NOTE The use of the latter criteria verifies conformance with this standard but does not infer that calibration of aparticular combination of instruments is interchangeable with any other combination.
The use of the latter criteria could allow a purchaser to use combinations of assemblies from differentmanufacturers with confidence.
The standard is applicable to:
– alpha surface contamination meters;
– alpha surface contamination monitors;
– beta surface contamination meters;
– beta surface contamination monitors;
– alpha/beta surface contamination meters;
– alpha/beta surface contamination monitors.
The latter two are equipment capable of determining alpha and beta contaminationsimultaneously and displaying the measurement of either:
Alpha (beta, alpha/beta) surface contamination meter
An assembly including one or more radiation detectors and associated assemblies orbasic function units, designed to measure alpha (beta，alpha/beta) surface emission rateassociated with the contamination of the surface under examination.
Alpha (beta,alpha/beta) surface contamination monitor.
This standard is also applicable to special purpose assemblies and to assemblies specificallydesigned for a surface of a particular nature.However, some of the requirements may need tobe amended or supplemented according to the particular requirements applicable to suchassemblies.
lf an assembly has been designed to carry out combined functions，it must comply with therequirements ‘pertaining to these different functions. lf，on the other hand,it has beendesigned to perform one function,and， in addition, it is also capable of carrying out otherfunctions，then it must comply with the requirements for the first function, and it would bedesirable for it to comply with requirements pertaining to the others.
This standard is not applicable to radiation monitors or meters designed to measure or detectbeta particles with Emax< 60 kev. The object of this standard is to lay down standard requirements and to give examples ofacceptable methods,and also to specify general characteristics, general test conditions,radiation characteristics, electrical safety, environmental characteristics, and the requirementsof the identification certificate for alpha,beta and alpha-beta contamination meters andmonitors.
