MINI-RADIAC

THE MINI-RADIAC IS A PERSONAL

DOSIMETER/RADIATION MONITOR. IT IS USED TO

DETECT ACCUMULATED DOSE AND/OR RATE OF

RADIATION EXPOSURE. IT IS DESIGNED TO ALERT

AND INFORM THE WEARER OF THE PRESENCE OF

GAMMA RADIATION BY FOUR DIFFERENT TYPES

OF WARNING/ALERT ALARMS AND DISPLAYS

WHICH INCLUDE A DIGITAL LCD DISPLAY, AN

AUDIBLE ALARM, A VIBRATING ALARM, AND

BLINKING GREEN LIGHTS.

MINI-RADIAC

THE MINI-RADIAC IS ABLE TO DETECT AND

DISPLAY LOW AND HIGH LEVELS OF

GAMMA RADIATION BOTH AS

ACCUMULATED DOSE AND RATE. THIS UNIT

WILL DETECT AND DISPLAY LOW LEVELS

SUCH AS NORMAL

BACKGROUND RADIATION ( 5 – 20 micro R/hr )

ALL THE WAY UP TO 999 R/hr AS EITHER RATE

OR DOSE.

MINI-RADIAC

THE MINI-RADIAC IS BUILT TO MILITARY

SPECIFICATIONS AND IS ACCURATE AND

EXTREMELY DUARABLE. IT IS

WATERPROOF, INTRINSICALLY SAFE FOR

USE IN EXPLOSIVE ATMOSPHERES AND IS

DESIGNED TO WITHSTAND AN ELECTRO-

MAGNETIC PULSE ( EMP ) THAT OCCURS

DURING A NUCLEAR DETONATION.

MINI-RADIAC

INTRODUCTIONTHE MINI- RADIAC CAN MEASURE AND DISPLAY BOTH

THE RATE OF EXPOSURE (RATE), (which is the amount of

radiation being measured at the moment) AND THE TOTAL

ACCUMULATED RADIATION DOSE RECEIVED (DOSE).

THE ALARMS:

THE MINI-RADIAC’S PRESET ALARMS FOR BOTH RATE

AND CUMULATIVE DOSE CAN ALERT YOU TO

HAZARDOUS CONDITIONS. WHEN AN ALARM

THRESHOLD IS EXCEEDED, THE DISPLAY WILL BEGIN

FLASHING,BEEPING AND VIBRATING.

AT THE REQUEST OF THE LOS ANGELES FIRE DEPARTMENT,

THE FOLLOWING LOW AND HIGH ALARM LEVELS HAVE BEEN

FACTORY PRESET.

DOSE RATE

LOW ALARM LEVEL: 2 mR/Hr

HIGH ALARM LEVEL: 10 R/Hr

ACCUMULATED DOSE

LOW ALARM LEVEL: 5 R

HIGH ALARM LEVEL: 10 R

ADDITIONAL FEATURES

THE ABILITY TO CHANGE ALARM LEVELS FROM THE FRONT PANEL

HAS BEEN DISABLED .

THE ABILITY TO RESET THE ACCUMULATED DOSE FROM THE FRONT

PANEL REMAINS ENABLED.

MINI-RADIAC QUICK STARTTO TURN ON, PRESS AND HOLD ON/OFF

* THE DISPLAY WILL SHOW THE NUMBERS 0,1,3,4, IN

SEQUENCE.

* THE DISPLAY WILL CHANGE TO THE RATE MODE;

THE WORD RATE WILL BE SEEN AT THE TOP LEFT OF

THE SCREEN.

MINI-RADIAC QUICK START CONT.

*TO CHECK THE ACCUMULATED DOSE

* PRESS DOSE; THE ACCUMULATED DOSE WILL BE

DISPLAYED

* WHILE IN THE RATE MODE, THE UNIT WILL

CONTINUE TO TO COLLECT AND STORE DOSE MODE

DATA.

*TO RESET THE ACCUMULATED DOSE TO ZERO

* PRESS BOTH DOSE AND CLR/TEST.

* THE DOSE WILL FLASH ALL ZEROS AND CLEAR

THE ACCUMULATED DOSE.

MINI-RADIAC* THE ALARM INDICATORS, ALARM , AUD AND/OR VIS,

WILL BE SEEN ONLY IF AT LEAST ONE OF THE

INDICATORS HAS BEEN ACTIVATED.

* THE UNIT WILL START COUNTING AND DISPLAYING THE

CURRENT EXPOSURE RATE. NATURALLY OCCURING

BACKGROUND RADIATION WILL CAUSE THE UNIT TO

DISPLAY A LOW READING. ( 5 - 20 MICROROENTGENS PER

HOUR )

MINI-RADIAC

• IF A b IS DISPLAYED, THE MINI-RADIAC IS NO LONGER FUNCTIONING

BECAUSE THE BATTERIES ARE ALMOST EXHAUSTED.

• IF NOTHING IS DISPLAYED, THE BATTERIES ARE DEAD. WITH NO POWER TO

THE UNIT, YOU MAY HAVE LOST ALL DATA IN THE MEMORY.

• THE GN LOCATED IN THE UPPER RIGHT CORNER OF THE DISPLAY IS USED

ONLY BY MAINTENANCE TECHNICIANS. IT’S SHOWN SO YOU CAN VERIFY THAT

THE ENTIRE DISPLAY IS OPERATING PROPERLY.

TESTING THE DISPLAY CONT.

CHECKING THE ALARM:

AT ANY TIME DURING THE CLR/TEST SEQUENCE OF NUMBERS:

• PRESS THE RATE KEY – THE ALARM BUZZER SHOULD SOUND AND

THE INSTANTANEOUS RATE LIGHT SHOULD TURN ON.

• PRESS THE DOSE KEY – THE ALARM BUZZER SHOULD SOUND AND

THE ACCUMULATED DOSE LIGHT SHOULD TURN ON.

• PRESS THE ALARM KEY – BOTH ALARM LIGHTS SHOULD TURN ON

AND THE ALARM BUZZER SHOULD SOUND.

MINI-RADIAC

AT THE END OF THE TEST SEQUENCE, THE BLINKING

9 WILL APPEAR, INDICATING THAT THE RATE MODE IS

OPERATIONAL.BACKLIGHT TEST:

PRESS AND RELEASE THE LIGHT KEY, THE DISPLAY BACKLIGHT WILL

TURN ON FOR ABOUT FIVE SECONDS. THIS FUNCTION IS MEANT TO BE

USED IN TOTAL DARKNESS: THE BACKLIGHT MAY NOT BE VISIBLE IN

DAYLIGHT OR NORMAL ROOM LIGHTING. LOW BATTERY INDICATORS:

* IF A BLINKING BAT APPEARS IN THE TOP LEFT CORNER OF THE

DISPLAY, THE BATTERIES HAVE NO MORE THAN 10 HOURS OF

USEFUL LIFE REMAINING. THEY SHOULD BE REPLACED AS SOON AS

POSSIBLE

* IF A BLINKING b IS DISPLAYED, THE UNIT WILL HAVE STOPPED

FUNCTIONING: THERE IS ONLY A ENOUGH POWER LEFT TO KEEP THE

MEMORY ALIVE FOR A SHORT TIME. IF THE BATTERIES ARE NOT

REPLACED AT THIS TIME, ALL DATA AND SETTINGS WILL BE LOST.

MINI-RADIACSOURCE FINDER MODE :

THE SOURCE FINDER OR CHIRP MODE ALLOWS THE UNIT TO LOCATE

AN ISOLATED SOURCE. AS THE UNIT IS MOVED CLOSER TO THE

RADIOACTIVE MATERIAL, THE UNIT WILL “CHIRP”. AS THE UNIT

APPROACHES THE SOURCE, THE RADIATION INTENSITY INCREASES,

CAUSING THE “CHIRP RATE” TO INCREASE.

ENABLING THE SOURCE FINDER MODE:

• PRESS AND HOLD THE “RATE” KEY UNTIL THE DISPLAY CHANGES

TO A FLASHING 1 .

• RELEASE THE “RATE” KEY.

EXITING THE SOURCE FINDER MODE:

• PRESS AND HOLD THE RATE KEY UNTIL THE DISPLAY CHANGES TO

A FLASHING 0 .

• RELEASE THE RATE KEY.

TURNING THE UNIT OFF:

• PRESS THE ON/OFF KEY

• OFF WILL BE DISPLAYED

• YOU’LL SEE - - -

• THE UNIT WILL TURN IT’S POWER OFF

COMPLETING THE TESTS:• WHEN THE MINI-RADIAC HAS PASSED ALL

TESTS, THE UNIT IS READY FOR OPERATION.

• IF THE UNIT FAILS ANY OF THE OPERATIONAL

VERIFICATION TESTS, CONTACT S & M
