Which Becquerels should be measured?

A recent report about the ground water of Fukushima gave the following report:

Groundwater from well No. 1-16 (pg. 3), Collected Dec. 12, 2013:

  • Cs-137: 1.8 becquerels per liter (Bq/L)
  • Co-60: 0.55 Bq/L
  • All β: 1,800,000 Bq/L

What is most striking is the difference between the total becquerels of Cesium-137 and the total of all Becquerels.   The total Becquerels is 1,000,000 times higher than the total of Cesium 137.  Nuclear reactors, particularly uncontrolled ones, make all the known elements  in all their isotopes.    If one assayed this water only for Cesium-137, it would meet “safe” levels.  I doubt that the water would be safe to drink>
