A biosensor to monitor radiation induced DNA damage on the ISS: risk assessment

for astronauts

 The project aims to further development of a yeast based biosensor system. 

The already existing system will be modified for the assessment of radiation 

induced DNA damage through the construction of genetically engineered yeast 

strains with enhanced sensitivity to radiation and coupled expression of the

green fluorescent protein (GFP). The project plans to develop both a novel

tape based detection system for continuous monitoring of radiation exposure

and a badge based detection system for occasional high-risk exposure.

In the current issue of the British periodical Spaceflight, there is a news-brief about a device, developed with sponsorship of ESA (the European Space Agency).

The new device uses modified yeast which give off light proportionally to the amount of DNA damage repair activity, and therefore the amount of ionizing radiation (of all types).

Its intended for use by astronauts (on the ISS) and possibly also by pilots & flight attendants on airliners.

 

I was not able to find anything about this on the ESA news web site -- can someone direct me to an address on the internet please ?

 

Thanks.
