Elton Parish Council raised fears over the marking of fluids with chemicals or radioactive nuclides to enable tracking through the subsurface.

Initially, the radioactive nuclides released by FNPA contained 21% [sup.131]I (half-life: 8 days), 2.3% [sup.134]Cs (half-life: 2 years) and 1.9% [sup.137]Cs (half-life: 30 years).
The results show that the radioactive nuclides were not released to the environment even though the containment pressure increases up to 1.2 MPa.
