Strontium-90 is main component of beta radiation in groundwater.

Recently 1.4 million Bq/liter of all-beta radiation (including strontium-90) was detected in groundwater near Unit 2 of the destroyed Fukushima Daiichi nuclear plant, a new record. Tepco, for some, reason, has not released the actual Sr-90 levels, though.

But Fukushima Diary has an entry stating that Tepco has released Sr-90 levels from groundwater near Unit 1, the sample collected Sept. 11. They found 7,500 Bq/liter of strontium-90, where 9,500 is all-beta. Strontium-90 only emits beta radiation.

It can be inferred that the main component of the increasing record beta levels is the extremely dangerous isotope strontium-90. Last March, Tepco found strontium-89 in groundwater also.

These strontium isotopes collect in bone marrow, and cause bone cancer, leukemia, and immune system damage. You can be sure that this groundwater will be entering the Pacific sooner or later.

  1. The 10th, TEPCO announced radioactive materials that emit beta radiation, such as strontium-90 from water in the observation well located on the sea side of the Units 1 and 2 Fukushima Daiichi nuclear power plant has been 1.5 million becquerels per liter detected. Date of collection is the 9th. In this well, there is on the rise the concentration of radioactive material, about three times the water was collected in November 4 of (the 540,000 becquerels), highest ever value is 1-4 Unit sea side well.

  2. TEPCO the 13th, the Fukushima Daiichi nuclear power plant radioactive water from the observation wells of seawall of the building Ocean side of strontium out beta radiation and radioactive material is 1.8 million per liter Becquerel announced that it had been detected. That record high value.

     According to TEPCO of the detected well water that is collected 12 days observation wells dug seawall No.2 east. In the past the well water taken from the well contaminated water concentration of was the highest. High concentration near contaminated water there is a tunnel that is accumulated. TEPCO, to the surrounding soil from where the broken contaminated water are seen to have oozed.

  3. Radiation in Fukushima groundwater skyrockets 3,500+ times over weekend — Just 5 meters from Pacific Ocean — No steps being taken to stop flow into sea (PHOTO)

    Some 63,000 becquerels of radioactive materials that emit beta rays, such as strontium-90, per liter have been found in groundwater in an observation well at the Fukushima No. 1 nuclear plant, the highest level at the well, Tokyo Electric Power Co. <9501> said Tuesday.
    TEPCO said that the radioactive materials were in a water sample taken on Monday from the observation well 5 meters from the coast, east of the plant’s No. 1 reactor. The previous highest radiation level in the well’s water was 67 becquerels, according to the company.

  4. The 20th, TEPCO Fukushima Daiichi nuclear power plant, from observation wells of the problems that have been detected in high concentrations all beta radiation such as radioactive material strontium 90, TEPCO detects a value of 1.9 million becquerels per liter of record today announced that it has.

    It was detected in groundwater collected from No1-16 observation wells, 19 days. From what has been detected 1.8 million becquerels 12 days, so that 100,000 becquerels concentration was increased in one week from the wells. TEPCO does not clearly explain why such as strontium 90 is continued to rise, but in the Unit 2 sea side, the location of the well can be seen that the direct contaminated water continues to leak from Unit 2.

    The east side of Unit 2, located near the (underpass and power cable passes) trench contaminated water of high concentration leaks extremely immediately after the accident of 2011 is the same well. It is located about 40 meters from the seawall. I seen flowing out to the ocean also has continued.
