Hello. I have to say, I stumbled upon your vids, and it may have been serendipity. Time will decide. I have yet to look at all, but for this one,...1 meter is near the radiation harmonic of the emission energy. Close to the source, less will enter, The dipoles formed have a circular motion, as well as linear acceleration, which is a congruent with all other matter. Therefore, near the "magic" distance, the most activity will be seen. Tesla called these points "Nodes". Thanks.
As I have understood the 1.022MeV energy is the limit for e-, e+ pair production. When the photon energy is larger than two times of rest mass of electron, the photon can interact with a nucleus forming e-, e+ pair. This is not, however, the threshold energy for neutron emission.
In photon induced neutron emission the energy of the photon has to be larger than the neutron separation energy of the nucleus. For example the neutron separation energy of 14-nitrogen is about 10.6 MeV.
well, i said that in the video - a neutron or proton can be emitted if the photon energy exceeds the binding energy of the loosest bound nucleon -> mass defect. however, at >=1,022 MeV, the photon can get to the core. if the excitation energy is too low to emit a nucleon, then a photon will be emitted.
It's not only cameras that these machines will damage, but probably brains as well by way of long-term blockade of neurogenesis.
Google : Depletion of New Neurons by Image Guided Irradiation
"Examination of the tissue with quantitative immunohistochemistry revealed a dominant low-dose effect on neuronal progenitors resulting in 80% suppression of neurogenesis. … the exposure of human subjects to doses often used in radiotherapy treatment could be damaging and cause cognitive impairments."
well, i guess it's reasonable to assume collateral damage with these doses of radiation. however, one has to see it in context - patients with CANCER receive this type of treatment - a disease which would otherwise be FATAL to them. surgery is not always an option, e.g. in widespread bone metastasis or when the tumor cannot be fully removed, e.g. in the brain or spine. the other option would be chemotherapy... which is much worse in my opinion. just google for "chemo brain".
@bionerd23, yes I agree. Risk-benefit analyses can certainly favor the use of interventions with potential harms if the harms of not using it are greater. On the flip side, there can be overuse of radiotherapeutic procedures that is best restrained by awareness of risks.
The way i see it in response to iamgoddard and your response, is they have cancer.... what have they got to lose ? Nothing, cancer is the worst thing you could ever get minus a stage 4 Virus like Ebola or something horrible like that.. My dad died from cancer in 1998 he didnt have the option for any treatments as it was way to late stage that and didnt have a lot of this stuff in 98. But what im saying is if i had cancer i could careless what these radiation machines do to me
I believe this is what's called 'neutron capture'. During the SL-1 criticality accidental, the gold (Au-197) wedding ring of a nearby victim was transmuted to radioactive gold (Au-198) and copper (Cu-63) in his cigarette lighter became radio-copper (Cu-64), and that's how it was proven that the SL-1 incident was a criticality event.
First youtube video covering the topic of Nuclear Photodisintegration? I think yes! Well, there is one other corny techno song on here with that name it looks like, but I'm definitely not counting that. Awesommeeeeee.
it depends on the neutron cross section - type crosssection.html into google and chose link from environmentalchemistry. that'll give you a (very rough and not e.g. isotope-specific) overview.
knowing the elements with their isotopes (which isotopes are natural and in the mix, how many percent of each isotope are in the mix, and what is the cross section for neutron capture of those isotopes?) contained in the gamma scout as well as the AMOUNT of them contained, (cont)
....and then double checking with the half-life of the activation products (has to be short, as activity dropped to background within just minutes, so this rules out long-lived activation products for the main amount of radiation emission and thus) would allow for a more detailed guess about what exactly got activated inside, but yeah... i dont know any of these data off the top of my head, would have to look it up all as well. :)
Lol. That is funny! You caused Your poor gamma scout to become meta stable. That was quite amazing to see. You should bring a second Geiger counter to detect the reaction from the first unit, or shield the gamma scout with a neutron reflector. Amazing video! I still think your fusion video was the best, but still, this is an amazing show!
nobody but the patient (who has a severe illness such as cancer that is being treated) should stay in there.
while it is sometimes permissible to allow e.g. a mother or a "helping hand" into the x-ray room or even stay there during a ct scan (with lead protection), nobody may UNDER ANY CIRCUMSTANCES be in the room with the patient. if the patient cannot remain alone, he has to be sedated or narcotized. if that doesnt work, he cannot be treated.
"geile" ...lol :D

isnt gamma scouts case made out of plastic? that could work as a moderator, right?

yes, but it's WAY too few / thin plastic. it barely does any moderation. would have to be many centimeters / inches thick...

How do you assess the risk of being in that environment? Because you're largely water/hydrogen and some of your particles could get knocked off too.
