The leak will be identified wherever the count on the Geiger-Muller tube spikes, indicating a large presence of gamma radiation coming out of the pipes.

Radiocarbon dating is used to determine the age of once-living tissue, including objects like string, rope, and boats, all of which were made from living tissue.

All living cells take up carbon-14, whether from photosynthesis or eating other living cells.

When a living cell dies, it stops taking in carbon-14, because it stops photosynthesising or eating, and then gradually over time the carbon-14 decays and is no longer found in the tissue. The half-life of carbon-14 (the time in which it takes from the radiation emitted from the source to be halved) works out to be 5,730 years.

Though the least powerful of the three types of radiation, alpha particles are nonetheless the most densely ionizing of the three.

That means when alpha rays can cause mutations in any living tissue they come into contact with, potentially causing unusual chemical reactions in the cell and possible cancer.

They are still viewed as the least dangerous form of radiation, as long as it's not ingested or inhaled, because it can be stopped by even a thin sheet of paper or even skin, meaning that it cannot enter the body very easily.

Gamma rays have the most energy and can penetrate substances up to a few centimetres of lead or a few metres of concrete.

They are therefore often used to fight cancer and to sterilise food, and kinds of medical equipment that would either melt or become compromised by bleaches and other disinfectants. In those situations, a gamma ray source is placed into the substance flowing through the pipe.

Then, someone with a Geiger-Muller tube above-ground will measure the radiation given off.

Even with such intense barriers, some radiation may still get through because of how small the rays are.

Though the least ionising of all the forms of radiation, that doesn't mean Gamma rays aren't dangerous.

They are likely to be emitted alongside alpha and beta radiation, though some isotopes emit gamma radiation exclusively.
