@Sinthia Domina Which first entry are you referring to? Do you mean how to read the first page?
by borrrden 3/26/2011 8:24:29 AM
Lots of places sending boric acid too..Diablo reactor in US for one.

@Sin The 1st reading it measuring the concentration of Iodine (I) and Cesium (Cs) in the air. They are measuring 4.0 bq/cubic meter of Iodine, and 1.2 of Cesium. The "reading" column is the actual radiation your body would absorb, which is 5.5 micro Sv /hour (uSv). So in 1 day you would experience 132 uSv, which is just 0.132 mSv /day.
by Jojo 3/26/2011 8:26:08 AM
yes Bq/m3 on iodine 131 45 kilometers away is 4.0.
by Sinthia Domina 3/26/2011 8:26:20 AM
@Sin Check out the top of p.3 for some eye-popping numbers.
by Jojo 3/26/2011 8:27:12 AM
And the uSv reading next to the spinach must be for the air/soil, not ingesting the spinach itself because it's measured per hour.
by Jojo 3/26/2011 8:28:51 AM
@Jojo Another possible interpretation would be the amount received if ingested, no?
by borrrden 3/26/2011 8:29:56 AM
Wow. I bet most people do not know what the hell any of this means.
by Sinthia Domina 3/26/2011 8:30:19 AM
@Sin Even though those numbers are (comparatively) low of .132 mSv/day, after 10 days you would experience 1.32 mSv. EPA sets an upper limit of 1 mSv for the general public for the year.
by Jojo 3/26/2011 8:30:24 AM
@borrrden I don't see why they would put that in uSv/ hour. For food it should be in uSv/ kg or something(?)
by Jojo 3/26/2011 8:31:02 AM
eah...I got it now. It is even more of a coverup than I thought.
by Sinthia Domina 3/26/2011 8:31:11 AM
RE: Becca's question - Do any of you understand boric acid to be effective in removing decay heat? My understanding is that it is simply a fission-prevention method, not a way of stopping decay heat. If that were the case, wouldn't they just keep enough on hand to stop the reactors?
by Hank Scorpio 3/26/2011 8:31:28 AM
@Jojo uSv per kg is never a valid measurement. What I was thinking was that once inside, you would receive that much internally per hour.
by borrrden 3/26/2011 8:31:52 AM
I suppose a better term would be "stopping." There is nothing that simply stops decay heat from occurring, correct?
by Hank Scorpio 3/26/2011 8:31:54 AM
they used it all already
by Sinthia Domina 3/26/2011 8:31:55 AM
@Sin So you see that they are measuring spinach at 1,110,000 Bq/kg of Iodine, and 1,500,000 Bq/kg of Cesium. The upper limit in Japan for Iodine is 300 Bq/kg, the upper limit for Cesium is 200 Bq/kg. That's pretty jaw-dropping. These compare to the maximums seen after Chernobyl, if not higher.
by Jojo 3/26/2011 8:33:19 AM
@borrrden I think you can. Water would be measured at Sv / L, meaning you drink 1 L you get x Sv. For food it should be Sv /kg: eat 1 kg, get x Sv.
by Jojo 3/26/2011 8:34:12 AM
@Jojo Food is different, 2000 per kg for iodine and 500 for cesium, but the point remains the same.
by borrrden 3/26/2011 8:34:27 AM
Sorry, here is the link to the article that states those limits. english.kyodonews.jp
by borrrden 3/26/2011 8:34:49 AM
yes Jojo...i don't think you are being an alarmist. I just don't know wh they haven't increased the evacuation zone. Google born to japan and Boric acid to japan and see the massive amounts being sent from all over the world.
by Sinthia Domina 3/26/2011 8:35:52 AM
*correction boron to japan
by Sinthia Domina 3/26/2011 8:36:19 AM
@borrrden Got it, thanks. Those are HUGE numbers, 3000 x the limit for cesium alone. 3000 x the limit.
by Jojo 3/26/2011 8:36:40 AM
And as far as I know, these amounts are not a big deal in the media anywhere are they?
by Sinthia Domina 3/26/2011 8:37:25 AM
@Sin I don't either. These are absolutely crushing radiation numbers, every time they eat this stuff it's dangerous. And that doesn't even account for the water, air, soil, milk, etc. in the area.
by Jojo 3/26/2011 8:38:01 AM
@Sinthia Domina I remember seeing those numbers reported on NHK.
by borrrden 3/26/2011 8:38:04 AM
@Jojo See page 9 of this document that states the actions being taken in response to those findings. www.wpro.who.int
by borrrden 3/26/2011 8:39:33 AM
Seems like the largest amount I had seen in the media was the plant in Tokyo at the research facility.
by Sinthia Domina 3/26/2011 8:39:39 AM
@Sin They are not a big deal in the media. Look at where I found the info: english.kyodonews.jp Can you find it? it's at the BOTTOM OF THE ARTICLE that talks about Tokyo drinking water. And the last paragraph is like ho hum oh by the way we found 1,500,000 Bq of cesium in some spinach!
by Jojo 3/26/2011 8:40:12 AM
NEWS ADVISORY: High radiation suspends work to fix Fukushima plant's No. 1 reactor
@borrrden Thankfully. But again how much of it was happily consumed by residents BEFORE they banned it? And there is no way to get such high numbers on spinach w/o having high numbers in the air/soil.
by Jojo 3/26/2011 8:42:41 AM
@Jojo The article also says it is a soil measurement and not a plant measurement. The report I heard was also that those were soil measurements. If that is the case (it might not be) then it is still serious, but not as serious as those levels being directly measured from spinach.
by borrrden 3/26/2011 8:42:51 AM
@borrrden Yes, the news report is on soil. Which are still incredibly huge. The 1,500,000 bq /kg is what they measured the other day on spinach. Same town, one was soil, this is spinach. With soil measurements of 163,000 Bq/kg, it will be difficult to grow anything in that town for a long time.
by Jojo 3/26/2011 8:45:36 AM
Hi guys, up again for a few minutes with those Japenese travelers who flew from Tokyo to China on my mind. Any recent news of how they received such dangerously high levels of radiation without being within 240km of the plant?
by Bev 3/26/2011 8:47:08 AM
@Jojo Yes, on that point I completely agree. Those high soil levels have a very good chance of severely damaging the region ecologically and economically for years to come. Probably fair to say over 100 years (there are unknown factors, such as crops that are resilient to uptake of cesium, advancements in the field of nuclear science allowing us to clean the soil somehow, etc). That is a secondary priority though, the first priority is of course the health and safety of all the residents.
by borrrden 3/26/2011 8:48:11 AM
In Kawamata Town the soil readings are 151,000 Bq of Iodine, 15,100 Bq of Cesium. Minamisouma City has 4850 Bq/Kg of cesium. Iwaki city has 1220 Bq /kg.
by Jojo 3/26/2011 8:48:19 AM
@borrrden They also are a big health concern now, esp. the elevated Iodine levels. Iitate Village is getting considerable radiation just from having 1170000 Bq of Iodine and 163000 Bq of Cesium / kg in their soil. It's not as much Sv as eating food/drinking water, but you're going to have SOME people that will drink the water, or in the shower, brushing your teeth, whatever. Kids in that town are going to drink from the tap, etc. And are they going to give bottled water to their dog forever? And you're going to get Sv every second that you are around the radiation in the soil, and these radiation readings are INCREASING. I don't know why they don't evacuate.
by Jojo 3/26/2011 8:51:46 AM
So do you all believe that the evacuation zone be expanded? Last I heard there was still 10,000 people in the 20-30km zone. I bet a lot have voluntarily left by now...if they can anyway. This is very very alarming and will have wide spread effects.
by Sinthia Domina 3/26/2011 8:51:49 AM
@Sin Iitate Village (that have these huge numbers), is 40 (!) km from the plant. I have seen isolated elevated numbers 75 km from the plant. They need to immediately check every town and FORCE evacuations. Otherwise you're just sentencing them to a death by cancer. Even the kids.
by Jojo 3/26/2011 8:53:16 AM
@Sinthia Domina - I interpreted the "suggestion" as double-speak for GTFO without inducing panic. I think they should've done that a week ago.
by Hank Scorpio 3/26/2011 8:53:52 AM
and they would need to have people going out in the snow to evacuate and be further contaminated.
by Sinthia Domina 3/26/2011 8:53:58 AM
Is is politics you think?
by Sinthia Domina 3/26/2011 8:54:19 AM
@Hank Scorpio WTF is up with a suggestion? Is it safe or not? If it's safe, why ask me to leave? If it's not safe, why not require everyone to leave? It's like a fireman going into a burning building but the people in a room don't know it's burning, and he says "do you mind leaving. No reason, just if you feel like it". ???
by Jojo 3/26/2011 8:55:23 AM
as in not to be seen as disrespecting the Japanese government by telling them what to do...or is it economics cause Japan is the worlds third largest economy?
