Japan-Fukushima Disaster

[Slycarter]

Does anyone know if there is alert about radiation in Thailand?

Have government monitored radiation into water along Thai sea cost?

Is there a refernce site with news about that?

No

I don't think there is anything to worry about.

The surface currents move at speeds of roughly two to four miles per hour (3 to 6 km/h).

General circulation of the currents is clockwise in the North Pacific

I haven't found any sea water monitoring data. There's a (quite sparse) aerial dose rate meter network maintained by the Office of Atoms for Peace. The readings can be found on their website, but in Thai only. Below are the latest figures from today, 4.4.2011, 17:00 Thai Time (err, as I write this, it's already past midnight in Thailand). I added the locations in English, so you can find your nearest measuring stations. Sorry that some vowels and tone marks were lost during copy&paste. The dose rates are reported in microSieverts per hour (μSv/h). If I do understand the linked document correctly, the alarm level is set at 0.200 μSv/h (200 nanoSv/h), which seems quite tight given the average dose rate of 0.155 μSv/h in Phayao (probably due to rocky mountains). Radiation levels vary regionally (altitude, geology), seasonally (well, not so much snow blankets in Thailand, but rainy season certainly has an impact), and also on short term (e.g. sharp rise shortly after rain sets in).

By comparison, the warning thresholds are 0.3 μSv/h in the Austrian radiation monitoring network, and 0.4 μSv/h in Finland. Germany uses location-specific thresholds, taking the regional differences in natural radiation levels into account.

BTW: Don't be surprised that two out of the 8 stations are currently not working. It's a good sign that they show 'no data' rather than repeating the last value ad infinitum. In summary, radiation levels in Thailand are pretty normal, as expected while western winds prevailed in Japan.

If something bad was happening they would not tell us, not good for business.

Until the first million people die of radiation sickness and then everyone starts noticing that there is something wrong here, then it`s business as usual and a hope for the best.
