Note: Some states also list species as threatened. Thus, in certain cases a state definition

would also be appropriate.

168. TOTAL EFFECTIVE DOSE EQUIVALENT (TEDE). The sum of the effective dose

equivalent (for external exposures) and the committed effective dose equivalent (for internal

exposures). (See effective dose equivalent and committed effective dose equivalent.) [Derived

from 10 CFR 835.2]

169. TRANSURANIC. Refers to any element whose atomic number is higher than that of uranium

(atomic number 92), including neptunium, plutonium, americium, and curium.

Additional optional information:

All transuranic elements are produced artificially and are radioactive.

170. TRANSURANIC (TRU) WASTE. Radioactive waste that is not classified as high-level

radioactive waste and that contains more than 100 nanocuries (3700 becquerels) per gram of

alpha-emitting transuranic isotopes with half-lives greater than 20 years. [Derived from 40

CFR 191.02, WIPP LWA]

171. TRITIUM. A radioactive isotope of hydrogen whose nucleus contains one proton and two

neutrons. The symbols for tritium are T and 3H; the latter symbol is more frequently

encountered.

If appropriate to the context add:

Used in thermonuclear weapons.

172. TYPE A PACKAGING. A regulatory category of packaging for transportation of radioactive

materials. Type A packaging must be designed and demonstrated to retain its containment and

shielding integrity under normal conditions of transport. Examples of Type A packaging

include 0.21-m3 (55-gallon) drums and standard waste boxes. Type A packaging is used to

transport materials with low radioactivity levels, and usually does not require special handling,

packaging, or transportation equipment. (See Type B packaging.) [Derived from 10 CFR 71,

49 CFR 173 Subpart I]

173. TYPE B PACKAGING. A regulatory category of packaging for transportation of radioactive

material. The U.S. Department of Transportation and Nuclear Regulatory Commission require

Type B packaging for shipping highly radioactive material. Type B packages must be designed

and demonstrated to retain their containment and shielding integrity under severe accident

conditions, as well as under the normal conditions of transport. The current NRC testing

criteria for Type B package designs (10 CFR Part 71) are intended to simulate severe accident

conditions, including impact, puncture, fire, and immersion in water. The most widely
