You arent getting it. Sr90 electrons dont travel that far in air. You cant measure it directly. You have to look at parent and daughter decay. Beta doesnt show up on a gamma spec. No cotizen scientist can provide analysis like the pros. This guy did shoddy analysis of trace levels in rainwater. Sorry no sale.

Beta doses are more a worker issue, not for those outside plant. Yet antinukes read of half life go ooh, aah, then project its dangerous fo us here in the US. Goes to show your lack of general rad protection knowledge. Like I said, Sr90 is a nonstarter in this case, just like prompt crit. Geez. Bang head here time....

Why not send the gamma spec of the Fukushima plume. No 185 keV. Berkley has it. Ask Per Petersen. Face it, any time you try to act like a nuclear engineer, you fall on your face. Thing is U Mich has a great program. It was there right in front of your nose.

Look at your diploma. I bet it was signed by Dr.Duderstadt, a nuclear engineer. I have his text book, Nuclear Reactor Analysis. You need to read it

Licey said: No. Im not even thinking Sr is a problem at this point. Its not a gamma emitter. You have to look at the parent and daughters.

Lucey----you continue to try to deflect, through out some science to cover your basic mistake of bringing up Sr90 in the context of a gamma scint discussion.

hmmmm daughter product of strontium, Y90 half life roughly 2.5 days.....decay method, ALL BETA.

And because of short half life, cells near a Sr90 (calcium mimicking bone seeker) will be assured of a near term double whammy.

2016-10-05T21:14:52.059-07:00

Im not the one making the claim. You made the claim, show your evidence. Doesnt it make you question how a criticality that yields barely a 1 lb TNT equivalent foece, produces a plume 1000 times that? The largest crit on record was ~1e18 spike fissions. Convert that to joules (1 fission ~ 200 MeV and ev ~ 1.6e-19 joule. Theres conversion apps on the web.

Your assertion doesnt match whats NOT there if it were true.

There are specific markers for this type of event and they are noticibly absent

I never said it was. Look, people get their panties in a wad over the littlest things that dont add up to a hill of beans. Ive got a chart of the nuclides on my wall and a large Table of Isotopes bible on my desk. Ypu know what i meant so dont even make something of it. Ive got millions of dollars of detector systems at my disposal. I do this for a living.

Are you trying to deflect your obvious "non knowledge" of basic isotopes, when you stated that Strontium should show up on a gamma source?

Not the mark of a NukePro, just a promoter of radiation. shame shame.

2016-10-05T19:59:33.257-07:00

Missing from WHAT? You presented no evidence, no gamma scint charts after Fuku. NOTHING. You presented nothing.

We want data/ You got it, present it, we will make a fair evaluation, and if wrong, change our hypothesis, like a scientist does.

Do you remember high school, when you were taught science, and the method, not just how to promote and industry???? Try hard nukist.

Ill add, "in industrial settings". Beta radiation, or relativistic electrons, are not highly penetrating in our atmosphere. The general public has this misconception of how much beta is needed to have any sort of risky dose. Just because an isotope has a long galf life doesnt automatically mean its poison. A Curie of K40 is much more dangerous than a microCurie of Sr90. You may squawk about the ICRP dose model, but it is the most accurate science. Those that disagree do not have a validated alternative model. The ECCR (Busby et al) model has no validation, which means their theory hasnt been benchmarked against standardized models as the ICRP dose model has been validated by such experiments. Now you may claim foul, or big nuke, or whatever outsider lamentation you choose. It soesnt make the fact that ICRP represents the best science available. I know you dont prescribe to the magic bullet theory of radiation interactions. There are necessary requirements for any source to be elevated to the level of concern. The first being the radiation levels must rise to the level where physical harm is more likely than mental harm. Many antinukes confuse the issue as somehow a true radiation effect. In actuality, its the mind, the belief structure that drives health. I know how to protect myself from large amounts of radiation in the workplace. There has never been the level of radiation outside my workplace where it would be a concern to the general public. Fukushima doesnt rise to that level. Neither does Carlsbad. 1 rem at the site boundary is basically 2x background in New Mexico.

Antinukes cry foul alot, but most of them lack the knowledge and understanding of real radiation risk, rather whats in their minds.

2016-10-05T11:50:42.840-07:00

Im looking at it all. Remember, no 185 keV line, its a clear indication no 235U in the air. Thus no aerosol of fuel, as no evidence to support. Get Tom to confirm.

2016-10-04T19:09:16.972-07:00

Also on those isotopic energies, the number in parenthesis is the relative fraction that specific energy occurs in the decay. The magnitude of the spike also depends on the mass of the isotope. Cosmic ray protons interact with the atmosphere and high energy gammas occur more frequently than from man made sources. Plus you really cant resolve to within 25 keV with anything other than an HpGe semiconductor detector or a hand held CZT detector that costs thousamds. So 700-800 keV may not mean a fission product but maybe c combination of overlapping peaks from other sources.

I dont think citizen scientists or the average layperson have the funding for high resolution gamma spectroscopy.

I use a code called GADRAS, and it generates background spectra based on NORM. Naturally occuring radioactive material. There is a huge 1430 keV gamma in NORM. Yup its from K40. Also there is a 2200 keV from natural Th232. The nat 238U is seen from alpha decay to Pa234m which shows up as a 1001 keV gamma and 770 keV as well.

So the 700-1000 keV is most likely from NORM and not Sr90.

2016-10-04T18:56:30.731-07:00

The 185.7 keV (actually 185.85) gamma from U235 is so dominant above all other spikes that if its missing, you can bet that ZERO fuel has aerosoled from Fukushima.

The Sr90 spikes could be from anthropomorphic uranium U238 that underwent spontaneous fission in coal. You might argue its a small likelihood, but from the sheer volume of coal burnt the last 150 years, its not a trivial amt.

You can work it out on a spreadsheet. Find the total tonnage of coal burned, the amount of nat U in coal on average, and the probability of spontaneous fission from 238U. Then apply the fission fragment fraction from Sr90 and you will have the Sr90 loading from burning coal. The answer might surprise you.
