Block of detection BDKN-200 is intended for measuring the power of the ambient dose equivalent Ḣ*(10) of neutron radiation and for measuring the neutron flux density.
Output signal corresponds to the standard interface:
• RS – 485 – detection unit BDKN-200 PD;
• RS – 422 – detection unit BDKN-200 DD;
The contents and the format of the data are defined in the report of the informational exchange DiBUS (www.doza.ru)
2.Energy range of detected neutron radiation is from 0,025 eV to 10.0 MeV.
3.The measuring range of PED of Ḣ * (10) of neutron radiation is from 0,1 mSv / h to 0.1 Sv / h.
4.Range of measurement of neutron flux density is from 0,1 up to 104 neutron / (c • cm2).
5.Limit of the basic relative error of the block is ± 30%.
6.Sensitivity of the detection unit is 5,0 imp/s at 1,0 mkЗv/h
7.Energy dependence of the block in the neutron energy range of typical neutron spectra is no more than 30%.
8.Time of setting up the operating mode is no more than 5 min
9.Duration of continuous work of the unit is not less than 24 hours
10.Algorithm for processing measuring data is a method of “moving average”. Integration time is 40 seconds. Exposure – 1.
