Calian Ltd
Development of a DNA -Based Dosimeter — Calian aims to further explore the capability of a biologically-based gel dosimeter to measure the mixed-radiation field in deep space. As deoxyribonucleic acid ( DNA ) provides crucial understandings to the biological effects of radiation, the proposed solution offers a device in which tissue-equivalent double-strand DNA breaks are used to estimate the quantity of radiation absorbed by crew members. The DNA -based dosimeter will also be able to qualify the type of radiation field by comparing single strand breaks with double strand breaks under various space radiation fields.
