Moving to the Albert Einstein College of Medicine in New York City, Gravekamp teamed up with radiobiologist Ekaterina Dadachova and colleagues to combine modified Listeria with the radioactive compound rhenium - 188, which they attached to an engineered protein called a monoclonal antibody that sticks to the bacterium.

Now, these archives have become important to a new generation of radiobiologists, who want to explore the effects of the extremely low doses of radiation — below 100 millisieverts — that people receive during medical procedures such as computed - tomography diagnostic scans, and by living close to the damaged Fukushima nuclear reactors in Japan.

And radiobiologists expect that the threshold «safe» dose will vary between tissues and between individuals. (scientificamerican.com)
