In recent years, scientists have been scaling up the power of the X-ray, using massive particle accelerators or synchrotrons to deliver much larger radiation doses.

近年来，科学家们利用大量的粒子加速器或者同步加速器来产生更大的辐射剂量，从而不断地提升X光射线的能量。

Of course, the clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula's newborn star cluster, Melotte 15.

当然，这些云气是由恒星风和辐射塑造成的，这些恒星风和辐射来自于星云新诞生的梅洛特15号星团的大量炽热恒星。

“What we know from experience is the psychological footprint from a nuclear disaster can not only be massive but in many ways greater than the effect of radiation,” Becker said.

贝克尔又说了：“我们能从历史经验中学习到核事故因为在人们心中早已有了根深蒂固的可怕形象，它所带来的影响远比放射物要大得多，多得多。

Even if the winds change direction, which is unlikely, fears of massive radiation poisoning throughout the region are vastly overblown.

In the year 775, the Earth was hit with a massive burst of radiation.

Sunday morning came another gaffe, when Tepco admitted that three workers who been exposed to massive doses of radiation had not been forewarned.
