Dyatlov Radiation- Effects and Autopsies [Part 17]

20 Sep

REMEMBER

The 4 variables:

Dose. The more radiation, the worse the symptoms.

Time. How long was the radiation exposure? Brief could be smaller impact, extended could be worse.

Shielding. How direct was the exposure? Drinking radioactive material will be worse than being exposed to trace amounts.

Distance. Being in the immediate vicinity of an explosion will be worse.

Also remember

Determining Dose of Radiation Exposure:

When cells are exposed to radiation, the number of mutations is increased. If mutations are passed down to children, this can cause genetic defects in the offspring (2).

A person who has absorbed very large doses of radiation has little chance of recovery. Depending on the severity of illness, death can occur within two days or two weeks (1).

Radiation Background: Exposure~ Not All Radiation is Scary/Harmful [Part 14B]

15 Sep

We have talked plenty about the potential sources of radiation. Let’s make sure we’re on the same page about the routes of exposure. And here’s why not ALL radiation is bad and harmful. The amount of radiation that will make a person sick is highly dependent on source, dose, distance, time, and shielding.

Radiation sickness occurs when high-energy radiation damages or destroys certain cells in your body. Regions of the body most vulnerable to high-energy radiation are cells in the lining of your intestinal tract, including your stomach, and the blood cell-producing cells of bone marrow (1).

Radiation Background: Decay & Half Life [Part 14A]

14 Sep

Alpha decay causes the isotopes to lose 2 protons and 2 neutrons. Hence, the atomic number of a radioactive isotope is decreased by 2 units and the atomic mass from 4 units. Heavy elements such as Uranium can undergo alpha emission.

During beta decay, the proton in the nucleus is transformed into a neutron and vice versa. If a proton is converted to a neutron, it is known as β+ decay.

gamma emissions do not change either the atomic number or the atomic mass of an atom. Gamma radiation is composed of photons. These photons carry only energy. Therefore, gamma emission causes the isotopes to release their energy.

Symptoms of Radiation

The initial signs and symptoms of treatable radiation sickness are usually nausea and vomiting. The amount of time between exposure and when these symptoms develop is a clue to how much radiation a person has absorbed.  After the first round of signs and symptoms, a person with radiation sickness may have a brief period with no apparent illness, followed by the onset of new, more-serious symptoms.  With mild exposure, it may take hours to weeks before any signs and symptoms begin. But with severe exposure, signs and symptoms can begin minutes to days after exposure (1).

Possible symptoms include (1):

  • Nausea and vomiting
  • Diarrhea
  • Headache
  • Dehydration
  • Fever
  • Dizziness and disorientation
  • Weakness and fatigue
  • Burns
  • Sores or ulcers
  • Hair loss
  • Bloody vomit and stools from internal bleeding
  • (bacterial) Infections
  • Low blood pressure

Don’t forget to read the prequel to this post!

Mastermind 

…And the touch of a hand lit the fuse/Of a chain reaction of countermoves/To assess the equation of you/Checkmate, I couldn’t lose/What if I told you none of it was accidental/And the first night that you saw me, nothing was gonna stop me?/I laid the groundwork and then, just like clockwork/The dominoes cascaded in a line/What if I told you I’m a mastermind?/And now you’re mine/It was all by design/’Cause I’m a mastermind…/…Strategy sets the scene for the tale/I’m the wind in our free-flowing sails/And the liquor in our cocktails/What if I told you none of it was accidental/And the first night that you saw me, I knew I wanted your body?/…So I’ve been scheming like a criminal ever since/To make them love me and make it seem effortless/This this the first time I’ve felt the need to confess/And I swear/I’m only cryptic and Machiavellian ’cause I care

I don’t really care for the following paper’s confusion about control vs. status. Or their lazy conclusion justifying a weak result with autistic TRAITS vs. a diagnosis. But there is a lot of interesting information about hormones here:

I promise the direction I’m going with this will make sense when you see the actual post. I’m setting up your foundational knowledge with this one.

Back, back, back in 2005, sitting in some Animal Science course (dairy cattle? Genetics?) I remember having an epiphany that this farm animal development and behavior we were learning about could be extrapolated to human sexuality. I mean, duh, obviously mammals have much the same processes, everybody knows that. But I hadn’t heard about a CAUSE of homosexuality. As far as I was aware, nobody could find a gene, environmental factor, or consistent theory of how it came to be. All I knew, is that it isn’t a choice, and queerness was an innate, unchangeable trait.

What we were learning went something like this:

https://pubmed.ncbi.nlm.nih.gov/2670872/

This particular research paper was written in 1989. So it wasn’t a new concept. I couldn’t understand why nobody had put the pieces together and declared the CAUSE of human homosexuality…

OK, so it’s not nailed down to a single cause. It’s complicated. But here is research that finds maternal hormones do play a part in gender expression children and sexuality of adults:
