Reply to Ferlazzo and Foray: About the Space Pup project.

We would like to thank Ferlazzo and Foray (1) for their very important comments and suggestions.

As the authors suggest, it would have been a good idea to expose our control sample to both Ramsar and Japan. When the control radiation level increases from 0.5 mSv/y (Japan) to 70 mSv/y (Ramsar) the difference between space and ground …
