Product description:

6150AD-b High sensitivity environmental grade γ Dose rate meter

6150AD-b high sensitivity environmental level γ dose rate meter by the German PTB laboratory scale, hailed as the world's best environmental level γ dose rate meter

* 6150AD-b high sensitivity environmental level γ dose rate meter by the low background, high volume plastic scintillator detector and host 6150AD 5 composition;

* High sensitivity: low 5nSv / h

* Extremely wide energy response: 20keV ~ 7Mev (remove the protective cover) 38keV ~ 7MeV (with protective cover)

* Simultaneous measurement of: the instantaneous dose rate, the average dose rate (to display the standard deviation of the average dose rate), the maximum dose rate and cumulative dose

* Dose (rate) alarm threshold adjustable (full scale)

* Automatic range conversion

* Inherent instrument background up 10nSv / h

Energy response curve remains flat benefits in a wide range:

Now the dose rate measuring instruments are calibrated with 137Cs source; that measuring instruments to respond to 662keV energy photons; per unit dose rate (μSv / h) corresponding instrument count rate cps; after a good scale; conversely; According to the count rate cps can be obtained dose rate of the current field; and the photon energy is not the same (eg 60Co), corresponding to the same radiation field instrument response dose rate (cps) is not the same, the response and the response of the instrument of 137Cs after comparison of the normalized curve is called the energy response curve. The actual measured radiation field is not a single energy field, but in a certain range having a field energy distribution, the so-called spectrum (see figure below different radiation field can Comparison of the spectrum), so the same instrument between the actual measurements of radiation field (137Cs radiation field is different from the time scale) and the results will be under a single can of 137Cs scale errors exist, obviously, the energy response curve in the flatter wider range, using the measurement results of the instrument of the obtained error is smaller.

Features:

6150AD-b high sensitivity environmental level γ dose rate meter of the 'mean' operating mode and 'dose rate measurements "operating mode compared to the more suitable for low emissivity measurement of the amount. Dose rate meter measuring system to work from starting by counting the number of pulses and measuring the time to get a mean average value shown to the level of response of the current value, the average value can be cleared by the operation and start over, when the probe is replaced or the average of the measurement system to be shut down to clear and start again.
