The Neutron Monitor 2222A He-3 measures both dose and dose rate
The Neutron Monitor 2222A He-3, Digipig, is a new version of the former famous model 2222A. To apply new IATA transport regulations He- 3 detector is used, with moderator containing polyethylene and boron plastic. Integration with SMD-technology give a very compact monitor including including μ-processor, memory functions and real-time clock. With these electronics a number of new functions have been integrated.
The 2222 is intended as a general purpose instrument for radiation protection purposes as well as for continuous monitoring of levels of neutron radiation in locations where permanent dose monitoring is required.
The instrument measures the neutron dose rate in the unit of mSv/h with approximately correct ICRP Sv response curve in the energy range from thermal eutrons to 17 MeV. The instrument is essentially independent of direction of the source and has a very low sensitivity to gamma radiation.
Each unit is delivered with calibration protocol. The dose rate is presented in analogue as well as digital form. The instrument is also measuring the accumulated dose presented in μSv and mSv.
Average dose rate values during 5 minutes intervals are stored in RAM-memory for up to 16 hours operation. The content of the memory can be sent to RS232 terminal.
The instrument is also equipped with five presettable dose rate alarm levels, one in each decade. Pulse output for an external counter can be connected to the unit for remote readings.
Win Pig
As an option the 2222 can be supplied with software (Windows PC) for usage in data communication applications. Data is transferred to a PC by a communication protocol. In addition alarm levels, date, time can be programmed remote via a PC. If a preprogrammed alarm level is reached the 2222 alerts the PC and forwards the alarm. WinPig software supports the PC application and gives advanced graphics to stored data.
