NHK World EnglishThe Japanese government has instructed all 47 prefectures to report the results of their environmental radiation observations every day.
Education and science minister Yoshiaki Takaki said on Tuesday that this follows the detection of unusually high-level radiation at nuclear power plants in Fukushima prefecture after Friday's massive earthquake and tsunami.
The prefectures are now asked to report their radiation data from monitoring posts at least twice a day and swiftly inform the central government if higher-than-usual readings are recorded.
Takaki said his ministry is to release the nationwide data at least twice a day, starting possibly on Tuesday.

While this is some good news, based on 15 years of dealing with air quality issues and running air quality monitoring networks, I have to comment twice a day sampling during an environmental event is not acceptable. Hourly rates would be ideal and I feel necessary. (I base this on the American premise of only doing what is required when it comes to public and environmental health)
