KING 5 News, Apr 18, 2016 (emphasis added): Leak worsens in massive Hanford tank holding nuclear waste; An emergency response is underway at Hanford, where a tank is leaking radioactive waste — A leak in a massive nuclear waste storage tank at the Hanford Site has expanded significantly, KING 5 learned this weekend… one former tank farm worker said the leak should be considered a major problem. “This is catastrophic. This is probably the biggest event to ever happen in tank farm history…” said former Hanford worker Mike Geffre… Until now, the leak found by Geffre was very slow. The liquid would almost immediately dry up… Sources told KING the disturbance caused by the pumping must have exacerbated the leak: essentially blowing a hole in the aging tank allowing the material to leak more quickly… “The hazards to workers just went up by a factor of 10,” said Geffre… [A current worker said,] “There’s always the question, ‘Are the outer shells compromised’”? The accumulation of waste in the outer shell also means the deadliest substance on earth is that much closer to the ground…

KING 5 News transcript, Apr 18, 2016: No one knows if the waste has already leaked into the soil… (Mike Geffre, former Hanford worker): “I was very shocked to hear that the tank had breached that significantly and that much waste had been [leaked?] in that short of time.”

KREM, Apr 18, 2016: ‘Catastrophic’ event at Hanford prompts emergency response; Over the weekend, a leak in a massive nuclear waste storage tank expanded significantly

KREM transcript, Apr 18, 2016: It’s being called a catastrophic leak at the Hanford nuclear site… Mike Geffre a former Hanford employee… told KING 5 that a leak of this magnitude is quote catastrophic… (Official:) “It’s just one more ‘Yes, the tanks are failing.’”

KIRO, Apr 18, 2016: Significant amount of waste leaks within Hanford double-shell tank… So far, no waste has leaked from the tank into the soil beneath it, but checks are ongoing… The DOE says the increased rate of leakage may have occurred because of work inside the tank dislodged material that was partially blocking leak sites.

KVEW, Apr 18, 2016: An alarm activated yesterday while crews were pumping waste from tank AY-102… The Department of Energy notified the state Department of Ecology that a leak detector alarm went off… The alarm indicated an increase in waste seeping from the primary tank into the space between the primary and secondary tank, known as the annulus.

KPLU, Apr 19, 2016: Increased Leakage From Huge Tank of Radioactive Waste At Hanford Sets Off Alarms — An apparent surge in leakage from a huge tank of radioactive waste set off alarms at the Hanford nuclear site… instruments detected a sharp rise of toxic brew in the space between the inner and outer tank walls.

Weather Channel, Apr 19, 2016: ‘Catastrophic’ Leak Found in Nuclear Waste Tank at Washington State Storage Site — An ongoing nuclear waste leak in Washington State has rapidly intensified over the past weekend, leaving workers scrambling.

Tri City Herald, Apr 18, 2016: Significant amount of waste leaks within Hanford tank; Leak estimates surge from 70 gallons to 3,000-3,500 gallons… An alarm for a level detector in the annulus sounded about 3:30 a.m. Sunday… It dropped by about three-quarters of an inch… raising the possibility that it might be leaking from the outer shell.

AP, Apr 19, 2016: “We’re continuing our checks of the tank to determine whether any material might be escaping from the tank itself,” said Jerry Holloway of Washington River Protection Solutions, which manages the underground tanks for the U.S. Department of Energy.

What works for 7 f

n the video above, viewers can watch as a Geiger Counter measures radiation from a Cobalt 60 source. Putting glass, aluminum and even lead sheets in between the Cobalt 60 and the detector makes no difference, as the Gamma radiation passes through all of them. This is what makes Gamma radiation so dangerous. It takes a very dense, very thick layer of lead (many feet thick) to stop Gamma radiation. Imagine what a particle of Gamma radiation will do INSIDE the human body, if this is the power it has OUTSIDE the human body.
According to Wikipedia; “Cobalt-60, 60Co, is a synthetic radioactive isotope of cobaltwith a half-life of 5.27 years. It is produced artificially by neutron activation of the isotope59Co.[3] 60Co decays by beta decay to the stable isotope nickel-60 (60Ni). The activated nickel nucleus emits two gamma rays with energies of 1.17 and 1.33 MeV, hence the overall nuclear equation of the reaction is
27Co + n → 60
27Co → 60
28Ni + e− + gamma rays.
Corresponding to its half-life the radioactive activity of one gram of 60Co is 44 TBq(about 1100curies). The absorbed dose constant is related to the decay energy and time. For 60Co it is equal to 0.35 mSv/(GBq h) at one meter from the source. This allows calculation of the equivalent dose, which depends on distance and activity.
Example: a 60Co source with an activity of 2.8 GBq, which is equivalent to 60 µg of pure 60Co, generates a dose of 1 mSv in one meter distance within one hour. The swallowing of 60Co reduces the distance to a few millimeters, and the same dose is achieved within seconds. (Inhaling or ingesting ANY radioactive materials makes them MUCH MORE DANGEROUS and increases the speed of a LETHAL or cancer causing dose, with even small particles that would not be lethal if exterior to the body.)
The high γ-energies result in a significant mass difference between 60Ni and 60Co of 0.003 u. The short lifetime contributes further to the high decay energy. This amounts to nearly 20 watts per gram, nearly 30 times larger than that of 238Pu.
decay scheme of 60Co and 60mCo.
The diagram shows a (simplified) decay scheme of 60Co and 60mCo. The main β-decay transitions are shown. The probability for population of the middle energy level of 2.1 MeV by β-decay is 0.0022%, with a maximum energy of 665.26 keV. Energy transfers between the three levels generate six different gamma-ray frequencies.[4] In the diagram the two important ones are marked.
Weapons Application
Car scanning using Co-60 gamma-ray device.
Cobalt has been discussed as a “salting” element to add to nuclear weapons, to produce a cobalt bomb, an extremely “dirty” weapon which would contaminate large areas with 60Co nuclear fallout, rendering them uninhabitable. In one hypothetical design, thetamper of the weapon would be made of 59Co. When the bomb exploded, the excess neutrons from the nuclear fission would irradiate the cobalt and transmute it into 60Co. No nation is known to have done any serious development of this type of weapon.
(For more information about the dangers of Cobalt 60 in ‘dirty’ bombs, and the horrors of having a substance like this out in the world, easily available to ANYONE who really wants it, via food irradiation plants, and testing devices such as the one shown above, click on the following link)…
There is no natural 60Co in existence; thus, synthetic 60Co is created by bombarding a 59Co target with a slow neutron source, usually californium-252 moderated through water to slow the neutrons down, or in a nuclear reactor such as a CANDU reactor, where the control rods usually made of steel are instead made of 59Co [10]59Co + n → 60Co
After entering a living human ( in food, air or water), some of the 60Co is excreted infeces. The remainder is taken up by tissues, mainly the liver, kidneys, and bones, where the prolonged exposure to gamma radiation can cause bone, liver, kidney or other cancers. Over time, some of the absorbed radioactive cobalt is eliminated in urine.[7]
Cobalt is an element of steel alloys. Uncontrolled disposal of 60Co in scrap metal is responsible for the radioactivity found in several iron-based products.[11][12] (This happens more often than you think)
In the above video an incident involving radioactive cobalt is discussed in India.
In 2000, a disused radiotherapy head containing a 60Co source was stored at an unsecured location in Bangkok, Thailand and then accidentally was sold to scrap collectors. Unaware of the dangers, a junkyard employee dismantled the head and extracted the source, which remained unprotected for a period of days at the junkyard. Ten people, including the scrap collectors and workers at the junkyard, were exposed to high levels of radiation and became ill. Three of the junkyard workers subsequently died as a result of their exposure, which was estimated to be over 6 Gy. The source was safely recovered by the Thai authorities.[13]
This does not happen just in foreign countries. It also happens in the USA. In August, 2012, Petco recalled several models of steel pet food bowls after US Customs and Border Protection determined that they were emitting low levels of radiation. The source of the radiation was determined to be 60Co that had contaminated the steel.[14] Many other incidents like this have happened in the USA, but there is no one tracking these, or monitoring where radioactive substances go that are sold for scrap.
