detect radiation if there is no particle. For example, if we are in a dental
office, and put a GeigerMonitor on the chair for it to receive an X-ray, it will
report radiation, but the radiation material (radiation source) is contained in this X-ray situation. Radiation fallout from Japan, on the other hand, is not contained.
The news did say radiation material was detected in Sacramento today http://www.fox40.com/news/headl... 阅读全帖 |
