removing uncertainties regarding the distribution, combustion and
mitigation of hydrogen as well as those concerning the behavior of
fission products, including iodine and aerosols.
aims to study of the effect of wind on accidental contaminating
releases from a nuclear power plant. The Tivano program (from the
French acronym meaning "Transfers Induced by Wind in Accident and
Nominal Operating Conditions) aims particularly at qualifying the CFX
calculation codes and the Sylvia software programs to better integrate
the effects of wind in the release calculations.
Radiation protection for human health and environment
The aim of the ALPAHA RISK program was to improve quantification of the risk of cancer and non-cancer diseases related to chronic external or internal exposure.
The ANTHOS project (Prerequisites for the use of mesenchymal stromal cells (MSC) combined with locally injected hydrogel and HS-mimetic for treating the side effects of abdominal-pelvic radiation therapy) aims to improve the effectiveness of MSC-based cell therapy in treating the severe side effects that may be induced by pelvic radiation therapy.
BioQuaRT (Biologically weighted quantities in radiotherapy) aimed to gain additional knowledge
regarding the dosimetry of ionizing radiation used in the medical field
in order to potentially reconsider the concept of absorbed dose.
The CAROL program consisted in studying stocks and flows of radionuclides in the environment.
The CURE (Concerted Uranium Research in Europe) project aimed to develop an innovative approach
that integrates epidemiology, biology, dosimetry, toxicology and
statistics to expand knowledge of the health effects of chronic uranium
exposure and produce a protocol for a collaborative European research
project on the topic.
The principal objective of the project is to develop a diamond dosimeter to measure the dose delivered in the minibeams used in stereotactic radiotherapy. This technique uses convergent beams of small size to very selectively irradiate a target of small dimensions (on the order of a square millimetre to a centimetre); they constitute a very-high-precision non-invasive treatment (unlike standard radiotherapy) useful for primitive or secondary tumours located near radiosensitive structures or difficult to access for surgery, such as the brain, spinal cord or lungs. These minibeams allow the total radiation dose distributed to the targeted tumours to be increased.
The study of external dosimetry in the Fukushima region (EDOFU) is a current research study (2014-2016) by IRSN aiming at better quantifying the evolution (in space and time) of ambient dose rates in the Fukushima region following the nuclear accident in 2011.

The consequences for a population and environment exposed to industrial pollution, especially if that pollution is radioactive, depend not only on the scale and type of the pollution, but also on the characteristics of the environment in which it occurs. This statement forms the basis of the Sensib radiological sensitivity project launched in 2004 by the IRSN Laboratory of Continental and Marine Radioecological Studies (Laboratoire d'Etudes Radioécologiques en Milieux Continental et Marin - LERCM). See also PRIME Project description, part of the SENSIB Project.
The project goal was to qantify the lung cancer risk after low radon exposure and low exposure rate and to make a synthesis from epidemiological and experimental data.
