Tritium
Tritium is a radioactive isotope of hydrogen. It is very rare in natural form, but can be produced. It is used in making self lighting watches, as well as hydrogen bombs.

How old is a bottle of wine if the tritium activity is 25 counts/hr and new wine has an activity 200 counts/hr The half life if tritium is 12.3 years.?
Asked by Mikki Jo
I don’t understand the question
What similarities and differences are there between Tritium and ordinary hydrogen?
Asked by Wiki User
- tritium is a radioactive form of hydrogen, used in research, fusion reactors and neutron generators.
- hydrogen can be used as an energy carrier and can be used as an integrated energy system for heat and electric energy production and as a chemical.
- both tritium and hydrogen are similar in that the nucleus of each of the tritium atom and the hydrogen atom has only one proton
- they are different in that tritium nucleus has one proton + 2 neutrons however the hydrogen nucleus has only one proton and no neutrons
How long does it take for 16.0 ng of tritium to decay to the point where 2.0 ng remains?
Asked by Wiki User
36 years.
It's half life is 12 years. That means in 12 years there will be 8ng left, in another 12 years there will be 4ng, and in another 12 years, there will be 2. 12*3=36
What is the advantage of using tritium with deuterium in a hydrogen bomb?
Asked by Wiki User
DT fusion has the lowest temperature/pressure of ignition of all fusion processes, and so is the easiest to start.
Is 5000 dpms the limit of tritium contamination for devices that require it to be turned into RAD waste for disposal or further evaluation?
Asked by Wiki User
No. DOE has set the limit at 10,000 dpm/100cm2 by wipe sample.
The first-order rate constant for the decay of the radioactive isotope tritium is 0.056 year-1 What fraction of the tritium initially in a sample is still present 50 years later?
Asked by Wiki User
N = N0 X e ^ (-kb X t)
where:
NO the initial amount = 100
kb is the constant = 0.056
t is the time = 50
I get 6.1 after 50 years.
Why is tritium illegal in the us?
Asked by Wiki User
Tritium is not illegal in the US, but as with other radioisotopes it is regulated. It has many legal uses:
- radiochemical tracer
- tiny amounts are used in neon lamps and signs to help them start faster and more reliably
- sealed ampules are used to make a phosphor glow to light watch and instrument dials ("safer" replacement for radium)
- electric activated neutron sources (used in petroleum and other industries)
- etc.
What is the role of tritium in a nuclear bomb?
Asked by Jkmyoung
Tritium gas is injected into the hollow weapon pit (the "core") to boost the nuclear yield of the explosion. Weapons that use tritium injection are called "boosted weapons".
Tritium has a half life of 12.3 years if 118mg escapes what percent of the spill will remian radioactive in 61.5 years?
Asked by Wiki User
3.13% will be radioactive at that point.
How do you calculate the mass of tritium?
Asked by Wiki User
Tritium has two neutrons and one proton: the mass is 3 amu.
As tritium gas is a radioisotope of hydrogen is it safe in a watch or keychain?
Asked by Wiki User
Yes; it would seem that the health hazard is very low.
What is the resulting nucleus if a tritium and a deuterium nuclei fuse?
Asked by Wiki User
Helium and a neutron:
D + T --> He + n + 17.59 MeV
What is the fraction of a sample of tritium that remains undecayed after fifty years?
Asked by Wiki User
This fraction is 12,5 %.
