Radiation of one form or another is a constant presence throughout our every day lives. Radiation, or the transmission and absorption of energy over a given distance, has proven an invaluable technology useful in applications for everything from heating our food to diagnosing and treating diseases.

All types of radiation can be divided into two categories: non-ionizing and ionizing. Non-ionizing radiation (consisting of radio, micro, and visible light waves) contains less energy and has a relatively small effect on living organisms that has only recently been studied. Ionizing radiation, however, contains a much greater amount of energy capable of ionizing atoms which can lead to harmful effects on living tissue. This category of radiation encompasses alpha and beta decay as well as neutron, X-ray, and gamma radiation.

Our project this year will focus on using a genetic circuit introduced into E. coli bacterial cells in order to detect and rapidly report the presence of harmful ionizing radiation. Ionizing radiation and radiation pollution is an important environmental problem that affects not only those working around radiation facilities but those dealing with the aftermath of nuclear disasters such as those at the recent Fukushima Daiichi nuclear reactor and the Chernobyl reactor.
