Health Hazards Acute and Chronic:RADIATION FROM SPARK GAPS IS
UNDETECTABLE AT ONE FOOT, LESS THAN 0.2 MR/HR AT SURFACE.THE
RADIATION EXPOSURE LIMIT FOR PERSONS IN UNRESTRICTED AREAS HAS BEEN
ESTABLISHED BY NRC AS TWO (2) MILLIREMS IN ANY ONE (1) HOUR
(MR/HR) OR 100 MILLIREMS TOTAL IN ANY SEVEN (7) CONSECUTIVE DAYS.
WHOLE BODY RADIATION EXPOSURE LIMIT IN UNRESTRICTED AREAS IS 500
MRFM/YR PER PERSON. RADIATION FROM SPARK GAPS IS UNDETECTABLE AT
ONE FOOT, LESS THAN 0.2 MR/ HR AT SURFACE.

Flash Point:NP
Autoignition Temp:Autoignition Temp Text:NP
Lower Limits:4 (H2 GAS)
Upper Limits:75 (H2 GAS)
Unusual Fire/Explosion Hazard:CONTAINS FLAMMABLE HYDROGEN GAS ENCLOSED
IN A METAL-GLASS SEALED ENVELOPE WITHIN THE IGNITION UNIT.

Spill Release Procedures:IN EVENT OF BREAKAGE, THE KRYPTON 85 WILL
DISPERSE HARMLESSLY INTO THE ATMOSPHERE. VENTILATE AREA TO
DISSIPATE KRYPTON 85 RELEASED FROM BROKEN SPARK GAPS.

Handling and Storage Precautions:AVOID BREAKING BY AVOIDING DROPPING OR
ROUGH HANDLING OF DEVICES CONTAINING KRYPTON 85. IN EVENT OF
BREAKAGE, THE KRYPTON 85 WILL DISPERSE HARMLESSLY INTO THE
ATMOSPHERE. UNISON SPARK GAPS CONTAINING KRYPTON 85 GAS CAN BE
IDENTIFIED BY THE LABEL "KR85" PRINTED ON SPARK GAP.
Other Precautions:RADIATION EMITTED FROM KRYPTON 85 SPARK GAPS IS
GENERALLY UNDECTECTABLE; THEREFORE, NO LIMITATION IS IMPOSED
CONCERNING NUMBERS OF GAPS WHICH CAN BE HANDLED BY AN INDIVIDUAL.
THE MINUTE QUANTITY OF RA DIOACTIVE MATERAL CONTAINED IN EACH SPARK
GAP QUALIFIES THESE DEVICES FOR EXEMPTION UNDER 10 CFR 30. 15.

Ventilation:LOCAL EXHAUSTVENTILATION RECOMMENDED.
Other Protective Equipment:NONE REQUIRED.

Waste Disposal Methods:TRANSFER TO LICENSED WASTE DISPOSAL SERVACE OR
ANY METHOD IN COMPLIANCE WITH TITLE 10 CFR, PART 20. WHEN DISPOSED
OF IN SMALL QUANTITIES, THE RADIOACTIVE SPARK GAPS PRESENT AN
INSIGNIFICANT RADIATION HAZARD. HOWEVER, NORMAL HANDLING OF SHOP
TRASH MAY RESULT IN HAZARDOUS ACCUMULATION IN THE DUMPING A REA.
(CONTD. SEE "ECOLOGICAL")

Toxicological Information:WHOLE BODY RADIATION EXPOSURE LIMIT IN
UNRESTRICTED AREAS IS 500 MRFM/ YR PER PERSON. DADIATION FROM SPARK
GAPS IS INDETABLE AT ONE FOOT, LESS THAN 0.2 MR/HR AT SURFACE.
KRYPTON 85 GAS, 0.6 MICROCURIE PER MILLILITER MAXIMUM. WARNING!
THE RADIATION EXPOSURE LIMIT FRO PERSONS IN UNRESTRICTED AREAS HAS
BEEN ESTABLISHED BY THE NRC AS TWO (2) MILLIREMS IN ANY ONE (1)
HOUR (MR/ HR) OR 100 MILLIREMS TOTA L IN ANY SEVEN (7) CONSECTIVE
DAYS.

Ecological:(CONTD. FROM "WASTE DISPOSAL") THEREFORE, FEDERAL OR STATE
REGULATIONS GOVERNING THE DISPOSITION OF RADIOACTIVE MATERIAL MUST
BE FOLLOWED. ESTABLISHED COMPANIES EQUIPPED TO DISPOSE OF THIS
MATERIAL IN THE APPROVED MANNER ARE IN EXISTENCE AND OFFER THEIR
SERVICES AT A NOMINAL EXPENSE. FOR FURTHER INFORMATION CONCERNING
THE HANDLING OF RADIOACTIVE MATERIAL, REFER TO FEDERAL REGISTER,
TITLE 10, PART 20, "STANDARDS FOR PROTECTION AGAINST RADIATION" OR
T.O.00-110N-7 "HANDLING AND DISPOSITION OF RADIOACTIVE ELECTRON
TUBES AND SPARK GAPS".

Federal Regulatory Information:UNISON INDUSTRIES IS LICENSED BY THE
NUCLEAR REGULATORY COMMISSION TO MANUFACTURE AND DISTRIBUTE SPARK
GAPS CONTAINING KRYPTON 85 RADIOISOTOPE. THE MINUTE QUANTITY OF
RADIOACTIVE MATERIAL CONTAINED IN EACH SPARK GAP QUALIFIES THESE
DEVICES FOR EXEMPTION UNDER 10 CFR 30.15 WHICH PERMITS POSSION BY
NRC GENERAL LICENSEES.
State Regulatory Information:IN THE DESIGN OF UNISON'S JET IGNITION
UNITS, SPARK GAPS ARE ENCLOSED IN A METAL-GLASS SEALED ENVELOPE
WITHIN THE IGNITION UNIT, AND ARE USED TO CONTROL THE ENERGY LEVEL
AND DISCHARGE CHARACTERISTICS OF THE UNIT. IT HAS BEEN DETERMINED
THAT, BY INCORPORATING A VERY SMALL QUANTITY OF RADIOACTIVE
MATERIAL WITHIN THESE SPARK GAPS, CONSISTANT IONIZATION AND
DE-IONIZATION LEVELS CAN BE OBTAINED, RESU LTING IN VERY UNIFORM
AND IMPROVED OPERATION OF THE IGNITION UNITS.
