Abstract

An optical is provided with reduced sensitivity to radiation, more particularly gamma radiation. The optical sensor is suitable for determining at least one parameter in a medium and includes a matrix containing a fluorescent dye. The matrix is supported by a transparent support. On the side facing the medium, the matrix has a layer soluble in the medium, which layer provides protection against radiation or damaging radiation products. The optical sensor is suitable for implementation in containers and laboratory products, such as disposable bioreactors for example, which are sterilized using gamma radiation.
