Radiation Spike In Unit 1 Discharge Canal & Groundwater Contamination Rises To Nearly Double Previous Reading


TEPCO hasn’t released radiation readings for the set of discharge canals for well over a year. This location has been historically quite high when they sampled it before. TEPCO announced that the sampling location in the discharge canal was again quite high while a downstream location was not. They provided no explanation where they assume the highly contaminated water is migrating to.
Beta radiation:  120,000 bq/liter
Cesium 134:  31,000 bq/liter
Cesium 137: 95,000 bq/liter
TEPCO closed off the end of the discharge canal early on in the disaster during attempts to block highly contaminated water from continuing to leave the plant. This admission comes soon after admissions of high level land side leaks from the unit 2 reactor building and increases in the sea front monitoring locations in the path of the unit 1 contaminated water plume.

Seafront well 1-6 began to rise again after it had begun to drop after the most recent typhoon. It nearly doubled, from 1.4 million bq/liter of beta radiation on the 23rd up to 2.5 million bq/liter on the 27th. TEPCO gave no reason for the jump.
This grouping of monitoring wells is assumed to be located in the path of the underground plume of highly contaminated water from unit 1. They are also located near the trench full of contaminated water near unit 2′s intake canal.
These ongoing findings of contamination spikes add to the understanding of how the damaged reactors are leaking. They also show how little TEPCO actually knows or admits about the extent of those leaks.
