Experimental Radiotoxological Laboratory (LRTOX)

The Experimental Radio-toxological Laboratory or LRTOX is located on sites at Pierrelatte and Fontenay aux Roses. It comprises 24 personnel including 7 researchers (physical chemists, biologists and veterinarians), several student doctorands and post-doctorates.

 


Summary

 

 

 

Context and research themes

 

The mission of LRTOX is to perform all types of experimental studies enabling acquisition of the basic data necessary to assess the levels and consequences of incorporation of radionuclides.

In particular, it coordinates the “health” input to the ENVIRHOM project, the objective of which is to describe the phenomenon of chronic accumulation of nuclides and to determine their effects on organisms.

 

 

Research axes


The main skills of the laboratory are:

  • The study of physical chemical characteristics of industrial compounds at workstations,
  • The biokinetic study of radionuclides after incorporation by ingestion, inhalation or injury,
  • Determination of the biological effects resulting from accumulation of incorporated radionuclides,
  • Determination at molecular level of the fixation and retention mechanisms for radionuclides in organisms.
