HPI Model 2010 is a Remote Area Monitoring System for penetrating
radiation. It consists of a number of wall monitors connected to
a console unit. The system permits real time observation and recording
of radiation levels at critical locations in facilities which have
the potential of producing high dose rates in areas which can be
occupied. These areas are found around reactors, accelerators, source
ranges, hot labs, nuclear fuel handling facilities, radiation therapy
rooms or any facility using large quantities of radioactive materials.
The Remote Area Monitor is an independent monitor designed for permanent
mounting. It measures the radiation level, continually displays
the doserate directly in absorbed dose rate units, displays the
status of the monitor, alarms if the dose rate exceeds the preset
level, and periodically transmits the information to the Console.
The tissue equivalent detectors measure the absorbed dose rate for
all penetrating radiation. Fail safe and self test features have
been designed into the system and the construction is ruggedized
and splash proof.
The wide range of five decades and the door and source interlock
capability, enable the monitor to be used as a warning or barrier
for high radiation areas as well as a low level monitor for occupied
