I was originally going to title this post "NASA Selects 12 Radiobiology Research Proposals" and announce the news, which I received today.
Thanks for the funding ($12M) NASA!
But then I recalled this video from last year with some of the background information associated with space radiation biology. Upon revisiting it today, it matched so well with my previous blog post (as well as with the NASA announcement), that I just decided to title this post as Part 2.
If you're a health physics denier of the radiation hormesis strain, you can just pretend the video and the facts described within it don't exist.
Welcome to the RIB Joint. A blog discussing science issues with an emphasis on health physics and agnotology. We'll try to keep 'em honest. So dig in!

What Will Some HP Deniers Do With This?
I'm referring to those health physics (hp) deniers of the radiation hormesis strain.
"This" is called SIRT6 and it plays a major role in DNA repair, especially Non-Homologous End Joining. (NHEJ). The graphic below depicts a double strand break (DSB) in DNA (top) undergoing repair by the NHEJ process. The next images, below the top one, depict how different proteins are recruited to effect the DSB repair. It doesn't include SIRT6 because the graphic is old.

Will The Presidential Candidates Discuss Science?
Maybe. We should demand they do, because people act upon what they believe. If you think there's a burglar in your house, you will behave a certain way. If you don't, you'll behave differently.
Bored? Play With This
It's a scale-of-the-Universe slider. Click the Start button and you will be on a scale of 10^0, which equals 1 (unless you're a math denier, in which case you can make up whatever you want).
Then move the slider button below the graphic to check out the expanse of the Universe. The power of 10 graphic gives you a sense of magnitude.
WOW!

Peter Gleick Addresses Science Denial
The video is from last year, but I've just come across it. The first part addresses fallacies that apply to all the science deniers, weather whether deniers of climatology, health physics, medicine, etc. The first cartoon he displays fits right in with my previous post!:
She Shows Leg, Brains Not So Much
She got a bruise on her leg from riding a bicycle. Her "cure"? She wraps a rock around her leg!
It's a radiation hormesis rock!

Never Seen A Cloud Chamber? Check This Out!
Cloud chambers show subatomic particle contrails which is short-hand for "condensation trails", usually associated with the condensation of water behind airplanes. This video starts off with just background radiation and then an Am-241 source is introduced. But the best is saved for last, Rn-220 (the video uploader says radium, but she meant radon).
Contrasting Medical Events
If you click on my link (upper right) to today's NRC event report, you'll see two contrasting medical radiation events.

Here's a short video from last year with Radiological Physics (think medical physics) Professor Cynthia McCollough. I hadn't seen it until today:
Arctic Sea Ice Reaches New Minimum, Unless You're In Denial
Based on over 30 years of records, and there's still more melting to go.

Why Are They Monkeying Around?
Zoos and aquariums find themselves in a sensitive situation on climate change. You see the planet is warming. But some of these facilities are concerned about discussing the issue (though others are not).
Why compromise because some people can't accept reality? Do what's right and discuss the science.

You Go Science Guy!
This video of Bill Nye ("The Science Guy"), has received a little media attention because Bill addresses biology deniers:
If you're a health physics denier (of the hormesis stripe), you aren't much different than someone who is in denial over evolution. In the case of biology, sex cell DNA mutations lead to the evolution of new species. In health physics, somatic cell DNA mutations lead to the evolution of new cell-types (cancer). The cartoon below could have included a health physics frame:
The graph below (from 2006 in the journal Science) shows the relative U.S. ranking in the global acceptance of evolution. If you squint, we're just up from the bottom. (Good thing we have Turkey!)

Radiation Hormesis - It's A Kind Of Magic
Yesterday I mentioned Jane Goldberg. When I was first learning about her I came across this video of her interviewing Philip Lipetz, PhD for her book. This video was completely different than the typical propaganda from health physics deniers (in this case related to the hormesis cult). Lipetz comes off as very intelligent, kind, and honest. He honestly states that his hypothesis is just that....a hypothesis (to be revisited below). Heck, I'd even say he's convincing:
Hints Of Rad Waste Migration From ORNL

Toshiba's CT Imaging Dose Reduction Software
Called AIDR3D, it has been tested at a facility in Florida, with good results.
Medical radiation exposures have soared in recent decades, and the medical community continues to take measures targeted at reducing them.
Here's a short, good video which explains how CT imaging software (generally similar to AIDR3D) is used for radiation therapy in a lung cancer case:
The anatomical planes she refers to are (she refers to the "axial" as the "transverse"):
The tattoos she mentions are very small permanent tattoos (can be removed by laser) and help to serve as "landmarks" (or "bodymarks"), to ensure repeated proper body positioning. Radiation doses are typically fractionated (total dose is delivered in fractions over days or weeks).

Radioprotectant Protein - TCTP
This is a good study showing how a particular protein (TCTP) is up-regulated following radiation exposure. A significant role of the protein is to prevent cell death, so it's no surprise that it's summoned after the exposure. Once up-regulated, it helps to prevent further DNA damage, a general phenomenon known as adaptive response.
One of the problems of all cellular-response-to-radiation studies, is that we don't know how to interpret the interplay among the many, various responses. Any particular study examines one unique aspect, but there are many studies and many aspects. And we don't know how many cellular response pathways are yet to be identified.
See my page "LNT Model & Radiation Studies" in the upper right, for a broader perspective.

The Christopher Busby Foundation For The Children Of Fukushima
Is a complete joke. I've blogged about him before (search his name), most recently asking "is he sane?".
Well, with this latest video, I won't need to ask that question again.
And that European Committee on Radiation Risk? Sounds impressive, but's it's just him and a few other whackos, including Yuri Bandazhevsky, who was jailed for taking bribes. Because he had also written papers exaggerating the health effects of radiation, his jail sentence has morphed him into a martyr in this cult.
If you haven't had your fill of conspiracy fantasies and fact-free health physics today, this should do the trick:

The Yeasty Boys
"Enthusiasm is the yeast that rises the dough"
Paul J. Meyer
Carl Zimmer describes how our distant cousin, yeast, has been used to discover a tumor shrinking drug.
In health physics we used yeast as an aid in understanding that the genes employed to resist ionizing radiation are different than those used to resist the more common damage of metabolism called metabolic oxidative damage (MOD). This is illustrated here (where "IR" stands for ionizing radiation, and H2O2 stands for hydrogen peroxide, one of the oxidizers).
Of course this is not surprising because the type and location of IR damage is different than MOD as are the cellular repair mechanisms. This was discussed here - "DNA Damage & Repair".
Can You Do Health Physics Deniers Next?
"The results showed that those who subscribed to one or more conspiracy theories or who strongly supported a free market economy were more likely to reject the findings from climate science as well as other sciences."
Mangling Radiation Health Effects To Confuse People

Some folks in Japan have a body burden of Cs-137 that is estimated to result in a dose of up to 0.85 mSv.
Oh, the suffering! HA!
Now, this guy, he suffered. (Not that radiation was causative).
(How do you get a dose "outside the body"? I think the writer means the total dose from internal and external radiation sources.)

The Hormies Should Be TREMling
I'm using short-hand...I'm referring to radiation hormesis proponents (health physics deniers) as Hormies, much like others refer to Intelligent Design proponents (biology deniers) as IDiots.
One of the tired old claims of Hormies is that radiation stimulates the immune system. Hey, guess what? If I cut you or introduce a pathogen it will stimulate your immune system! That doesn't make cutting people or infecting them a good thing!
On top of that, chronic stimulation of the immune system (chronic inflammation) is associated with increased cancer risk. Silly Hormies.
A recent study shows how the gene TREM-1 can promote a chronic, low level state of inflammation and increase the cancer risk in mice. The link between chronic inflammation and cancer risk isn't new, this study just adds to the existing knowledge base.
(For more info on radiation effects on the immune system see my page "Radiation Stimulates The Immune System So LNT Is False", upper right).

Atomic Ideologies Insights blog has a post on the subject. I have a separate page devoted to it, where I compare it to creationism (Biologists are hiding the truth! Evolution is a lie! It's a conspiracy! HA! HA!).
This article on world-views is timely. It's no coincidence that strongly religious people tend to deny biology, strongly pro-fossil fuel people tend to deny climatology, and strongly pro-nuclear (as well as strongly anti-nuclear) people tend to deny health physics.
It's human psychology....motivated reasoning, anchoring, confirmation bias, etc.

DNA Damage & Repair
Here's a great video explaining DNA damage and repair mechanisms. It's from Prof. Jim Boyne of the University of Bradford. Unfortunately, what that means is that in addition to technical jargon, you've got heavily accented technical jargon. If you're not up on basic molecular biology, you might want to pass. If you're wishy-washy you might want to read this first.
He does a good job (though not intentionally) of addressing a common health physics denialism claim that goes something like:
1. We have lots of DNA damage happening all the time.
2. Some event happens causing low dose radiation exposure.
3. There is no increased risk from the radiation because of 1.
Mathematically, it's like claiming 100,000 + 1 = 0, whereas the correct answer is 100,001.
Radiation's Long Term Effects On Pediatric Cancer Patients
Bone marrow transplant is often prescribed for kids who have leukemia or other blood cancers. Typically, just before the transplant the child is given total body irradiation in order to help kill any cancer cells and to suppress the immune system so that it doesn't attack the transplanted cells.
Here's a recent study which show some of the later effects of the irradiation (doses typically 1000-2000 rad range)

NYT Covers Increased Medical Radiation
Yesterday, I had a post on how some cardiologists have reduced radiation exposures. The New York Times has a good background article on the broader issue, and the author explains some of the underlying psychology which has led to the increase in the exposures.
Patients getting a radiation-based diagnosis or treatment enjoy modern medicine and can't feel any DNA damage. The costs are usually covered by a third-party (insurer), so the patient is not very cost-of-test conscious. A doctor is focused on whatever brought the patient to him/her in the first place and also wants to utilize all tools at his/her disposal to avoid a malpractice suit. The doctor may also profit from more testing.
But as my earlier post discusses, the situation is improving.
The U.S. FDA is actively involved.

Cardiologists Dramatically Reduce Radiation Exposures
In the last half of the 20th century, when someone wanted to know how much annual radiation dose a typical person receives, it was easy to recall....360 mrem (close to the number of days in the year).
But things change and by the early part of the 21st century the average is 620 mrem! (I have no mnemomic for that).
The culprit for the increase was medical radiation exposures. People were living longer, enjoying more advanced medical technologies, doctors wanted to avoid misdiagnosis for tort reasons so they wanted more imaging, etc.
Now some cardiologists at the Mayo Clinic have revised how they do their cardiology, with an average dose reduction of around 40%. They are tracking patient radiation doses and opting for lower quality, but sufficient imaging.
By publishing their achievements others can mimic.

Fukushima Data "MIxed"?
That's the headline of this AP article. The butterflies (as larvae) eat lots of contaminated vegetation from the Fukushima area and we see mutations. Humans in a neighboring city don't eat lots of contaminated vegetation, so they have low levels of contamination. Why is this "mixed"?

The second is an estimate of internal doses from the residents of Minamisoma, located 14 miles north of the Fukushima Daiichi nuclear plant. The vast majority was <1 mSv.

Chromosomal Translocations & Personalized Cancer Care
There's some promise in identifying the specific translocations and targeting for personalized care. The article points to one problem...how to know which translocation is causative and which is correlative. Another problem, is if cancer has developed, those cells mutate pretty uncontrollably, so that by the time you identify a personalized therapy, some cells have evolved and may not be a suitable target.

Allison - Radiation & Lack Of Reason
On his website he has posted two criticisms, one aimed at Japan and the other at Germany (look to the right, under "Downloads and links"). His basic rationale is that since DNA can repair itself, radiation shouldn't be feared. But DNA doesn't always repair itself with 100% fidelity, that's why there is a risk of cancer from a single photon (though the risk is very, very, very low). Low doses of radiation pose a low risk of cancer, they aren't harmless.

"This is the truth about the radiation count in Fukushima in the exclusion zone. It is sad that there is a cover up on information that should be made public that is not being made public.That Japanese government along with Mr. Noda as the center of all of this are and or seem like a bunch of terrorists that are getting away with all of their illegal activities without anyone trying to stop them in any way. All what they are doing and how they are running the government in Japan will slowly cause a lot of people to get and or die. Their actions are purely evil in every way!!!"

Nuclearphobia
The Economist has a blog post with that title. It gets the big picture correct, that there are a lot of unwarranted fears about things nuclear. But some of the justifications aren't very good...like mentioning how low the doses are to evacuees, which would be higher had they not evacuated. The author quotes a doctor who seems to be an LNT denialist. He doesn't seem to understand that there is an epidemiological threshold which we can't see below, but because we understand that ionizing radiation IONIZES DNA, it is rational to conclude there is no effect threshold.
