観測データ / Observed Data(FLASH)

ここでは、International Medcom社のガイガーカウンターInspector Alertを使って計測した値をリアルタイムで公開しています。このガイガーカウンターはセシウム137でキャリブレーションされており、セシウム137のみを検知した場合は310cpmで1μSv/hです。

On this page, we are publicizing the realtime readings taken by International Medcom’s Inspector Alert geiger counters. These geiger counters are calibrated to detect only cesium-137. When detecting only cesium-137, 310 cpm (counts per minute) is equal to a dose of 1 μSv/h.

As our project continues, we plan to build a sensor network and display our results here. Currently, the main purpose of this page is to monitor the operation of the system. We are gathering this data in partnership with Safecast.

Below are the readings converted to μSv/h (dosage).


These data are also being publicized by both Safecast and Yahoo!.
