Worldwide distributor of NSN parts and consumables located in the USA.
An inclosure, including two or more electrodes, in which a flow of electrons may occur through a vacuum or a contained gas. The electronic conduction takes place either by means of electrons emitted from a cathode or by ionization of the contained gas. Includes phototubes (photoemissive type only), geiger-mueller tubes, traveling wave tubes, cathode ray tubes and microwave tubes (klystron, magnetron, or the like). Excludes items whose primary purpose is to produce light energy. Also excludes photoelectric cell; and semiconductor device (as modified).

routes of entry: inhalation: yes skin: yes ingestion: yes
reports of carcinogenicity: ntp: no iarc: yes osha: no
health hazards acute and chronic: cobalt as radioactive: significant skin
cont may rslt in burns. Rapid estimation of amt of internal contam
is dfclt/imposs when alpha/pure beta emitters are involved.
beta/gamma rays are cancer causing agents. Naus, vomit & diarr for
high acute doses. Cobalt as metal: acute: cont derm & brthg dfclts.

explanation of carcinogenicity: cobalt: iarc mono on eval of carcin risk
of chems to man, vol 52, pg 363, 1991: grp 2b. Animal: pulm fibrosis
(blood efts).
effects of overexposure: hlth haz: inhal of dust can cause pulm symps
such as wheezing, irrit of upper resp tract & hypersens rxns
(asthma). Skin cont w/powder may cause adenitides, esp in creases
of elbows, knees, ankles & ne ck. Cont w/eyes may cause conj.
ingest may prdce hot sensation along w/vomit, diarr & naus.
chronic: allergic (supp data)
medical cond aggravated by exposure: healing of damaged tissues may be
prolonged. Disorders of skin & upper resp tract may be worsened by
expos to cobalt; administer preplacement & periodic med exams
emphasizing these functions.
First aid: eyes: immed flush, incl under eyelids, gently but thoro
w/plenty of running water for at lst 15 mins. Skin: immed wash
affected area w/soap & water. Inhal: remove expos pers to fresh air,
restore &/or su pport brthg as needed. Ingest: never give anything
by mouth to someone who is uncon/convlsg. High oral fluid intake
(at lst 1-2 glasses) of water should be admin & induce vomit.
