IGS
The ILL Graduate School coordinates the ILL's PhD activities. The ILL acts as host to a body of students studying for PhD degrees, selected members of its staff co-supervise students' thesis projects, generally for a period of three years.
ILU
The Industry Liaison Unit is the point of contact for industry looking to use the ILL's suite of instruments for proprietary research. The unit may initiate dedicated partnerships for technological R&D with consortia involving academic and industrial partners. In 2016 the ILU dealt with an extremely varied workload, due to the launch of operations on the new industrial instrument D50.The ILL's strain imager SALSA is also available to ILU on a part-time basis.
IMPS
Imaging MultiPlexed Spectrometer.
Internal exposure
Internal exposure occurs when the source of radiation is inside the body. It results in internal irradiation. The source may have entered the body by inhalation, ingestion or a skin injury, and then spreads throughout the body. This is called internal contamination. The contamination continues until the radioactive substances have disappeared from the body (a more or less rapid process) by natural elimination, radioactive decay, or medical treatment.
Ionising radiation
The radioactive elements present in the environment emit alpha, beta and gamma radiation as they decay. Gamma rays are electromagnetic waves; alpha and beta radiation are particles (a helium nucleus and an electron, respectively). This type of radiation produces ionisation in the matter through which it passes; it is therefore potentially dangerous for living organisms.
IRSN
The French Institute for Radiation Protection and Nuclear Safety
The IRSN is France’s public service expert in the field of research on and the expert assessment of nuclear and radiological hazards.
