Equivalent Dose Meter SM-3-D
Mobile equivalent dose meter for measurement of gamma radiation as surrounding dose equivalent rate easy handling acoustic impulse signalisation large measuring range compact enclosure

The portable equivalent dose meter SM-3-D is customized for determination of the surrounding dose equivalent rate of gamma radiation. The operation of the equivalent dose meter SM-3-D is very simple, which means that the user does not necessarily require any experience with radiation measurement technique. Due to its compact design the equivalent dose meter SM-3-D is very popular among installers and technicians. Average values of the current equivalent dose can be determined in one minute by means of a quick-test. The equivalent dose meter SM-3-D is equipped with an auditory impulse signalisation, i.e. the decay rate can be claimed acoustically by the equivalent dose meter. The detection of gamma radiation by means of the equivalent dose meter SM-3-D is applied in various areas, e.g. environmental conservation, construction industry, measuring engineering, waste disposal, recycling etc. Thus the equivalent dose meter SM-3-D has multiple application options and helps installers and engineers measuring potentials of nuclear radiation. Here you will find an overview of all equivalent dose meters.

Here you can get some general knowledge

Which measuring units are common in fields of radiation protection?
We have no sense for the recognition of ionised radiation. Thus for the detection of radiation a measuring device is necessary. In order to evaluate the effect of radiation knowledge about radiation forms and energy as well as about radionuclides in the human body are necessary. For example the activity measurement alone does not give any indication about biological effects or dangerousness of radiation.
