The Hong Kong Observatory enhances the content of e-Bulletin on Educational Resources

A new issue of e-Bulletin on Educational Resources has been published and distributed to thousands of subscribers through emails today (17 March).

The e-Bulletin has been enriched with a new column - 'Radiation tidbits'. The column's first topic is 'Air Travel and Cosmic Radiation'. Hong Kong people enjoy traveling. However, do they know that radiation at high altitude is higher than that on the ground? Does it reach a hazardous level? For the details, please read:

Mr. Poon Hoi-to, Senior Scientific Officer of the Observatory, said: 'Radiation is invisible and untouchable, but is closely related to our daily life. Its applications range from electricity generation, medical treatment, industry, agriculture, architecture, archaeology, to general consumer products.' To know more about radiation, please look at:
