52.   A KLM spokesman said that the radiation was within the legal limit of five mSv, and said that only airline staff were exposed.

53.   KLM acknowledged never telling the passengers, but insisted that the radiation was not excessive.

54.   Mahmoud Barakat, head of the Arab Nuclear Commission, told The Associated Press he has no reason to believe there is dangerous radiation on the borders.

55.   Nuclear waste containers dumped by the Soviet Union into arctic waters appear to have leaked, although the radiation is not an immediate threat, researchers said Wednesday.

56.   Radiation is the latest attempt to avoid this complication.

57.   Radiation near Jupiter is far more severe than previously estimated, raising concerns about the survival of future probes, NASA reported.

59.   The radiation is not measurable from Earth or any previous spacecraft to visit Jupiter.

60.   This radiation is not optically visible, but it can be detected by instruments on satellites.
