Project Abstract
Ionizing radiation and radiation pollution is an important environmental problem that not only affects those working around radiation facilities, but those dealing with the aftermath of widespread nuclear disasters such as those at the Fukushima Daiichi nuclear reactor. Penn State’s team project designed and constructed a genetic circuit introduced into E. coli bacterial cells, in order to rapidly detect and report the presence of harmful ionizing radiation. We are working to create a robust and reliable biosensor that utilizes the lambda phage lytic-lysogenic switch as the radiation sensor. When the sensor detects radiation, it triggers one of three fast acting reporters we developed based on the concept developed by Imperial College’s 2010 iGEM team will be triggered. Each of the reporters features a different enzyme/substrate reaction (ß-galactosodise/ß-D-galactose, ß-glucurodinase/ß-D-glucuronide or C23O/catechol). We believe that the final construct may have the potential to rival current radiation detection methods, such as digital dosimeters.

.Brainstorming
In the first few days of summer, we began discussing ideas for our project. Some of our first initial thoughts were to modify bacterial photosynthesis using the BCHM gene or to engineer a serotonin sensor. We thought about making a bacterial fuel cell by using Geobacter as a sacrificial anode. We also liked the idea of using bacteria to perform intelligent tasks, like mathematical arithmetic. The last idea we developed was to engineer a bacteria that would be able to detect radiation. The team spent a few days researching these topics to determine how plausible they would be and we finally unanimously agreed upon the bacterial radiation detector. With our full thoughts focused on this topic, we began looking into this idea further and discovered that the Penn State 2007 iGEM team had used the lambda phage system to also develop a bacteria that would test for radiation. However, they were not able to fully assemble their device or test it and we thought that we would be able to build upon their initial foundation.
.Research
After deciding to follow up on the bacterial dosimeter idea for our project, we as a team we had to first do some research on the effects of ionizing radiation in order to better determine what exactly we would be detecting. Currently all living organisms are exposed to a relatively low dose of radiation; this amount is so negligible that the negative effects are unnoticeable. The problem with ionizing radiation occurs when one is exposed to a high dose for a short period and/or low doses over an extended period of time. The International Commission on Radiological Protection (ICRP) recommends nuclear industry employees to limit ones yearly exposer to 50 mSv, or 100 mSv over 5 years.1 One international study, composing 15 countries and encompassing 598,068 nuclear industry workers, found that an increased risk of cancer exists. Specifically, 99% of those tested were exposed to less than 50 mSv of radiation per year, and 1-2% of these cancer related deaths may be attributable to this exposer. It’s also estimated that 100 mSv of cumulative radiation exposer would result to a 5.9% increase chance mortality.2 1. Cardis, E.
