1 Thomas Borak: Radiation can provide injury to humans.

2 Dr. Borak said that this dosimeter monitors doses of radiation a person receives, and transmits up-to-the-minute information to a computer.

3 Thomas Borak: When you're delivering radiation to a cancer patient, you're trying to deliver an extremely high dose to the tumor.

4 Thomas Borak: There is concern that they would develop a cancer if they're exposed while they're outside of their space vehicle to a solar particle event.

6 Borak added that the dosimeter is in the testing phase and hopes it will provide valuable improvements to radiation dosimetry in the coming years.

7 With support from the National Space Biomedical Research Institute, Dr. Borak is developing a device to monitor and warn astronauts of radiation in space during extended missions.

8 Cancer patients here on Earth who undergo new forms of radiation therapy using protons or carbon ions, said Borak, could also benefit from the dosimeter.
