It has recently been shown that exposure to nocturnal intrusive light (NIL), even at very low levels, leads to physiological changes. These include lower levels of the hormone melatonin, which could increase the risk of many diseases, including prostate cancer (PC). The population and the urban authorities are currently facing this concern, but the scientific bases are practically non-existent, because of the lack of exposure data to the NIL in the population and their rare application in research.

We propose an innovative project that focuses on the study of the statistical links between the occurrence of CP and the level and the spectrum of the NIL near homes and in bedrooms. The research will be applied to the population living in the territories of Montreal. The research will involve:

a. the development of multispectral remote sensing techniques, including the scientific exploitation of color images taken by astronauts from the International Space Station and other satellite datasets;

b. the use of LANcube, an instrument capable of measuring NIL on multispectral and multi-angular basis and the refinement of data analysis techniques;

c. numerical modeling of the propagation of NIL in the urban environment;

d. in situ validation of NIL derived from the combination of remote sensing and modeling;

e. the exploitation of PROtEuS databases, an imposing case-control study on the environmental causes of CP.
 
This transdisciplinary research project links the natural sciences and engineering to the health sciences. To do this, Marie-Élise Parent, epidemiologist at Institut de recherche scientifique (Québec) will work in synergy with Martin Aubé, worldwide recognized researcher in the field of detection and numerical modeling of artificial night light.
