The High-Radiation Lives and Risks of Nuclear-Nomad Subcontractors 96

Harperdog writes "Gabrielle Hecht has an interesting piece on the subcontracted workers of the nuclear energy industry, in Japan and elsewhere. These workers face far more exposure to radiation than salaried workers; in Japan, 90% of the nuclear workforce is contracted. This is an eye-opening look at a practice that 'carries exceptional risks and implications. And until these are recognized and documented, complex social and physiological realities will continue to be hidden.' A good read, but I would like to know how the Fukushima 50 are doing."

  • If companies contract this work out, rather than have in house workers do it, they are much less responsible for the long term consequences. It simply makes good business sense. You can argue whether or not the contractors fully understand the risks that they are taking and the likely outcomes, but at the end of the day it's a free market system and if they are willing to put their lives and future on the line, then let them do it.
    • If the contractors aren't being made aware of their cumulative radiation exposure levels and possible risks, then NO. The "free market system" is not a reason to let people into hazardous environments without knowing wtf they're doing.

      If they know exactly what they're getting into, then it is hard to argue against letting them do it, but it still feels cheap.

      It reminds me of the Foxconn situation where workers were committing suicide just so that their families could get the insurance money. Only this time

    • Radiation work in the US is regulated by the NRC, workers are required to wear a dosimeter that will be analyzed and a report given to the worker annually or however long the dosimeter can collect. All the workers I came in contact with were aware of the risks and the additive nature of the radiation. There is a hard limit that the NRC sets for exposure and once that limit is met the worker is not allowed to come in contact with radioactive materials.

The electronic dosimeter is read when you exit the RCA and the tld is read every few months. That exposure becomes part of the worker's permanent record (form IV) . The NRC has rules about exposur

    I was under the impression that in the U.S., at least, radiation dosage was tracked on a lifetime basis via a Nuclear Regulatory Commission database, REIRS, and anyone working at a nuclear facility, even on a contract basis, has to have the numbers from their dosage monitoring submitted to it. I don't think you can get away with laying them off and then someone else rehiring them while pretending they're a new person, because their dosage will get filed under the same social-security number in REIRS.

And someone will notice pretty quickly if John Doe consistently gets a lower dosage than the rest of the guys working where he does. And he'll get fired pretty quickly.

          Falsifying the SSN may be easy with other jobs but the background check for a nuclear facility is a bit more thorough, the only way this might be possible is if the employment application and NRC paper work are not cross checked.

      • You better believe there's some conniving going on. It shouldn't be so easy for workers to falsify information. If it is easier than it ought to be, as seems likely, that's almost certainly because the employer purposely make a hash of the monitoring system, and neglected to fix obvious flaws. Even just being too cheap to do any maintenance can provide plenty of opportunities to cheat as the system slowly breaks down.

      The Japanese have a centralised dosimetry system developed by Chiyoda Technol Corporation, the GD-450 glass badge and FGD-650 reader/central computer server. It's used by the Japanese nuclear industry, hospitals, civilian background monitoring etc. For example, they handed out 230,000 glass badges to civilians last September, so the system can handle large numbers (ave. dose was 0.26 mSv over 3 months). Also, the badges contain an ID printed on the front and hidden inside, to prevent tampering. So it seems the Japanese do have a well organised centralised system to monitor worker doses.

      Also, the IAEA released a Fukushima Daiichi status report on 2 November 2011, it contains a table of worker exposures (table 3). The highest doses in September, involved 7 workers who got 20-50 mSv (the ave. dose of 1047 workers was 1.8 mSv). I can't imagine gypsy workers could get substantially higher doses and in much greater numbers (unless they all falsify their glass badges and swim in the spent fuel pools). So I seriously doubt the article's allegations.

          At least in the USA, the number of deaths from exposure to radiation is roughly four in the last 50 years. Those three Navy guys killed when they screwed up SL-1 maintenance, and one guy who died at a fuel rod manufacturing plant.

          Before that, of course, there were deaths in Los Alamos due to radiation exposure in several accidents post-WW2 and pre-1960. Half a dozen or so.

      They're also often smaller companies, because that effectively caps potential liability (or more accurately, shifts it onto the government/population). If a huge company fucks up and causes a $50 billion mess, they might be on the hook for $50 billion, but if a smaller contractor does, they declare bankruptcy, their $500 million in assets get seized, and someone else is responsible for sorting out the remaining $49.5 billion of the mess.

        Don't know about elsewhere, but down here, your employer is liable for anything that happens at his plant that is work-related.

        * High or Very high levels - severe radiation poisoning, die within hours or days, maybe a few weeks if you're unlucky - so wouldn't still be in the hospital.

        * Moderate levels - something very similar to sunburn, might be in hospital for a short time for treatment, have increased risk of cancer developing, but that will take 5 - 25 years. People in this category would have been out of the hospital in maybe April or May of last year.

        Well, the truth is we don't know much about these ranges. The vast majority of the cases of whole body exposure are either survivors of Hiroshima or Nagasaki, or are among the early clean up workers at Chernobyl. I.E. amounts and types of exposure are for the most part poorly documented, as are subsequent care and outcomes. On top of that, it's a fairly small number as such things go, so it's hard to say clearly where the bottom of the 'Moderate' category is. There's just not enough data.
         
        And I haven't adressed the difference between whole body dosages and point dosages like the women exposed to Radium while painting watch dials. Or hospital workers exposed to ongoing low dosages of X-rays over extended periods...
         
        Making the problem even more difficult is the fact that the media (and Wikipedia, and Slashdot commentary) seem to treat all radiation more or less the same - when nothing could be further from the truth. Alpha, Beta, Gamma, neutron, X-ray... all ionizing radiation, all with subtly different effects. The same goes for length of exposure, whole body doses received over short periods are going to be different than those received over long periods, even if the absolute exposure is the same.
         
        All we really know is Exposure Is Bad, and try to avoid these levels.
         

        * Low levels - No immediate health effects. Increased risk of cancer in 5 - 25 years.

        * Very low levels - No health effects, essentially no increased risk of cancer (maybe something like .01 percent increased risk, but so close to zero as to be effectively zero increase in risk of cancer).

        Here, we see the same problems as above - you're acting as if there are clear bright lines between the categories. There isn't. Most importantly, the boundary between (your) Low and Very Low levels is fuzzy and poorly understood.

        Yep. My wife does payroll for a company that does work on reactors. Those guys make very good money; hourly rates of $30+, plus per diem and time-and-a-half/double-time as appropriate. The "poor, uneducated" workers GP was referring to easily make twice as much or more than I make as an experienced engineer.

  • A nuclear story mdsolar did not submit. At least it will put nuclear power in a positive light. We all know it needs that now since the SOTU did not even mention nuclear.....
  • Günter Wallraff, a investigative journalist, uncovered turkish laborers were 'used' for a similar purpose in German nuclear plants in the 80ies:

    Disguised as Ali, Wallraff took on jobs as laborer in construction firms, on farms, janitorial service, and even as a day laborer in a nuclear power plant. In the publication of his 2-year adventure as Turk in Germany, LOWEST OF THE LOW, Guenther Walraff later revealed that the Turkish workers at the power plant were not even provided the same amount of protect

  • I was in the nuclear field in the Navy many years ago, and if one of us (highly trained, expensively trained, hard to hire otherwise, etc) received too much exposure, we became normal enlisted men, of no use to the nuclear area. So when any task with high radiation exposure, 'normals' were assigned. The assumption was that these men would never get this expose again. Really, there is no other way.

    In the USA, In the 8 months or so prior to a refueling outage, through the first couple weeks of an outage, a huge amount of "construction" work is undertaken at a plant involving maintenance, inspections and repairs. A plant that has a couple hundred full time employees will bring on hundreds of contractors, sometimes a thousand or so total. These contractors make their very good living going from plant to plant for pre-outage and outage work. They make way more money than the average IT worker, I can tell you 7-10 years ago it was $50 to $120 an hour, and during the actual outage there would be 10 or 12 hour days for the first couple weeks, that's time and a half and usually gets to double time overtime per week. Those skilled tradesmen made serious coin. The plant issues dose meters and film badges and monitors the rad exposure of all workers, and *already knows* the dose for each area and type of work, there is no faking of exposure nor even possibility of doing so. The federal NRC has an office on site to oversee work, dose, compliance.

    • Skilled trades doing outage work can make serious bank!

      Fortunately the trades are despised by the US education system so the shortage of tradespeople (women can weld boilers and pipe too!) keeps wages high.

    Quote from Admiral Hyman G. Rickover, U.S. Navy, (27 January 1900 – 8 July 1986) was known as the "Father of the Nuclear Navy".

    I'll be philosophical. Until about two billion years ago, it was impossible to have any life on earth; that is, there was so much radiation on earth you couldn't have any life — fish or anything. Gradually, about two billion years ago, the amount of radiation on this planet—and probably in the entire system—reduced and made it possible for some form of life t

    The IAEA Status Report 2 November 2011 contains a table of worker exposures. In March 2011, 98 workers (out of 3742) received more than 100 mSv. But that was related to the initial disaster. By September 2011, 7 workers received between 20-50 mSv, the other 1039 workers received far less. The average dose to workers in September was only 1.80 mSv (people in Denver get 12 mSv a year).

    Even if there are "hidden" unmeasured gypsy workers, their doses could not be highly in excess of permanent salaried workers, unless they go swimming the spent fuel pools. The radiation levels at Fukushima Daiichi is now far lower then it was in March, so it's very hard to accumulate high doses unless you enter the reactor buildings. It's likely those few who enter the reactors are the trained staff conducting surveys and they well monitored.

    The Japanese introduced the GD-450 (glass badge) radiation dosimeter about 10 years ago, it's manufactured by Chiyoda Technol Corporation and is used throughout Japan's nuclear industry and hospitals etc. Dosimetry measurements are, from what I read, uploaded to a central computer (FGD-650 reader and server computer system). The badges contain the users ID printed on two stickers, one on the front and another on metal frame hidden inside the badge, presumably to prevent tampering.

    They handed out 230,000 glass badges to civilians in Fukushima Provence last September, so clearly the centralised system can handle large numbers. For example, 36,767 glass badges handed out in Fukushima City revealed an average dose of 0.26 mSv over 3 months. I'm pretty sure this survey is run by the Japanese Ministry of Health, it would be easy to share the worker data if it's not already.
