11.   He added that risks from radiation doses to unborn children are minimal when compared with other risks during pregnancy.

12.   He noted that one type of archaea microbe can survive radiation doses millions of times higher than would kill a human.

13.   In addition, as the technology improves, the radiation dose in digital mammography may be slightly lower, and lowering the dosage has been a continuing goal.

14.   McAnaw noted that there is still no agreement on the optimum radiation dose.

15.   The crews were exposed to enormous radiation doses during their flights over the reactor. . . .

16.   The larger problem, he said, is predicting the radiation dose from an unfolding accident.

17.   The radiation dose you receive depends on how plutonium enters the body.

18.   A nuclear plant worker received an excessive radiation dose while working with spent fuel, but he was not seriously injured, officials said Thursday.

19.   A radiation dose of about two roentgens a year is considered acceptable.

20.   As a result, the workers instantly received radiation doses nearly two times higher than the annual safe upper limit for Ukrainian nuclear plant employees, officials said.
