Follow-up to: Report: Plutonium ratio 200 times higher than gov't says -- Detection made 50km south of Fukushima Daiichi (RESULTS)

Title: Fukushima Isotope Data
Source: Global DIRT
Date: April 2011

This data was taken by a Global DIRT assessment team of the Fukushima I Nuclear Power Plant. Data was collected using a Berkeley Nucleonics Corporation SAM 940 Defender / Revealer. Data was collected up to within 50ft of the plant’s fence. The map below represents only readings which contained isotope levels (about 2000 of the 2900+ current readings). Be sure to check back as this page will be constantly updated.

Title: Fukushima Radiation from Tepco Nuclear plant 25km out
Source: Global DIRT
Date: April 11, 2011

Question: Oi, could you put some units on your map page? Numbers by themselves aren’t terribly useful, or meaningful.

Answer: the units are in CPS which measures background radiation, the CPS the unit receives is in the beginning, then the rest per isotope. The best way to calculate dose rate from CPS for the average human would be .87 per thousand CPS.
