CHAPTER - I
INTRODUCTION
{Radiation Survey Meter} Type: RM701N is a G.M. Detector based, battery powered, hand-held, general
Purpose radiation Survey Meter. This will be useful for dose rate measurements in nuclear installations,
Radiochemical plants, Reprocessing plants, etc. Additionally it will be useful in medical, agricultural, industrial
and other installations where radioactive isotopes are used for a variety of applications. This product is designed
around a Microcontroller Chip. It is provided with alpha Numeric LCD display for indicating the dose rate in
digits, dose rate as a bar graph, cumulative dose in digits. It covers wide range from 0 to 10R/hr in two range with
auto ranging. This unit has a facility for storing the data into built-in EEPROM along with real time. The stored
data can be recalled on to the display or transmitted to PC.
Some important features of this unit:
 ConformstoANSIN42.17A performancespecificationsforHealthPhysicsinstrumentation(portable)&
compliant.
 It is designedaround Microcontroller Chip.
 Uses energycompensated GM Counter.
 Rangechange over automatic.
 Accuracy+/-15%withCO60.
 Facilitatesstoring recallingof readings and transmissionofreadings to PC.
 Workson 6V(4x1.5V) dry cell batteries.
