This experiment aims to evaluate the effect of reduced cosmic radiation (ɣ-rays, muons, neutrons) on the viability of bacterial communities recovered from high purity D2O in the absence of externally added nutrients.

To this end, the proposed experiments will take advantage of the low levels of ambient radiation that can be achieved in subway facilities with the objective of analyzing microbial growth, and simultaneously, determine by ICP-MS the possible metabolites present in the system. These studies will make it possible to determine the effect of such radiation on the bacterial life cycle.
