Radiación ionizante en Medicina: Radiodiagnóstico, Radioterapia y Medicina Nuclear. Parte 2.

#Medicina #Nuclear
De forma natural, estamos expuestos a radiación ionizante. De media recimos 2,2 mSv/año y esta radiación proviene principalmente del Radón que es un gas noble procedente de la desintegración del Radio que está presente en todos lados.
De hecho, el Radón puede acumularse en espacios cerrados, lo que resulta peligroso, y por eso hay que ventilar las habitaciones.

#Medicina #Nuclear

⬇️⬇️ABRO HILO⬇️⬇️
Lo primero es diferenciar entre Radiodiagnóstico (RD), Radioterapia (RT) y Medicina Nuclear (MN).
La RD usa Rayos X para tomar "imágenes" para el diágnostico (bastante obvio😉). Son "imágenes anatomicas".
La RT usa Rayos X (más energéticos que en RD) para eliminar tumores.
Y la MN usa radiofármacos tanto para diágnostico como para terapia. Los radiofármacos son radionucleidos unidos a moleculas (Glucosa, ...) y que son inyectados en el paciente (sí, el paciente se convierte en una fuente de radiación☢️). En diágnostico, se usan principalmente ...

1) THREAD: What to expect if the #US 🇺🇸withdraws from #NATO? At the Körber #PolicyGame, we discussed this scenario w/ high-level officials and experts in coop w/ @IISS_org - here are the summarized results for the Twitterati community: (have mercy, it’s my first thread!)
2) We wanted to know: How would Europeans react in such a situation?What are interests and red lines? Thus, we invited a 🇫🇷, 🇩🇪, 🇵🇱,🇬🇧, and 🇺🇸 team to play our scenario. Crisis in the #South, Crisis in the #East - were #Europeans able to get their act together w/out the 🇺🇸? 💪 🇪🇺
3) The short answer is: willing yes ❕but able❔ First, most teams focused on reversing a #US withdrawal from #NATO by all possible means, offering the 🇺🇸concessions that were unthinkable before - from #trade to #energy. But what if that doesn’t help? 🤔

Why aren't Americans taking about the foreign influence in the US government that continues to send our men and woman to fight immoral wars?

#Trump when he campaigned for president, before he decided to let Adelson fund his campain!

Adelson was one of the biggest donors to Trumps presidential campain. Adelsons company saved 670 million dollars from the massive republican tax break. Adelson did not support the Iran deal & wanted the US embassy moved to Jerusalem.

Adelson has a direct line to #potus!

Adelson has private in-person meetings & phone conversations about once a month with #Trump!

Adelson used his access to move the embassy in Israel to Jerusalem and cut aid to Palestinians.……

Tonight on the @CNN #climateforum, Democratic candidates will talk through their plans to rapidly transition our country to clean energy. We’re guessing we’ll hear a lot about #renewables & carbon pricing. But what will they say about #nuclear energy?

Will they mention that it’s the largest source of carbon free electricity in the US?

#climateforum @wolfblitzer @ErinBurnett @andersoncooper @ChrisCuomo @DonLemon
Will anyone point out that, considering the scale of the challenge, we should get rid of fossil fuels before even thinking about getting rid of nuclear?

#Thread on the alleged Israeli strikes on #PMU bases in #Iraq
First Israeli strikes on #Iraq since 1981 major assault on Iraqi #nuclear facility Tammuz that ended the Iraqi nuclear program
The announced strikes or incidents are 3 till the moment, yet it's unknown whether there were more during the past few months. The Iraqi government seem to prefer ignoring the whole thing, yet the PMU deputy commander Abu Mahdi AlMuhandes was pushing for a clear stance
PMU commanders had a decision not to speak till yesterday, they were expecting a statement by the PM
@AdilAbdAlMahdi over the incidents, when this didn't happen #AlMuhandes issued his statement that infuriated the PM

In a nuclear explosion the human body is irradiated by

1⃣ major-burns due to thermal radiation & not caused by ionizing radiation

2⃣ thermal burns from infrared heat radiation
these would be the most common burn type experienced
the #nuclear threat to humans is devastating but does it do to our #environment?

Russia's #Nuclear Agency now confirms 7 dead from its nuclear accident.

Fascinating declassified b/g on Severodvinsk: #CIA, #NRO, National Archive docs to follow here.

The announcement brings the number of deaths caused by the blast to seven… via @WSJ
@WSJ For starters, where #Severodvinsk is:

"The information about the increased radiation, first published on Thursday at 14.23, was removed from the city authorities’ portal Friday afternoon and is now just a dead-link." — @NilsenThomas, The Barents Observer
@WSJ @NilsenThomas During the Cold War, Severodvinsk is where the USSR built its Typhoon class of submarine -- made famous by Tom Clancy in "The Hunt for Red October."

1. From 1942 to 1996, the US spent 5.5 trillion $ for #nuclear weapons, which means 5,500 BILLION dollars (in constant 1996 dollars). On average, 98 BILLION dollars per year
2. 5,500 BILLION$ spent by US bwt 1942 and 1996 for #nuclearweapons exceeds the combined total federal spending for:education;training;employment&social services;agriculture;environment;science,space, technology;community development;law enforcement;energy production&regulation.
3. these data comes from the top-notch work "Atomic Audit" by @AtomicAnalyst: They refer to 1942-1996, no fresh data are available. These data just refer to the US: we would need data about #Russia as well

One more clarification here, somewhat related to the Warren-Cheney dustup. And that is the difference between "preemption" and "prevention." We have NEVER had a "preventive" #nuclear strategy. If that's what Cheney is arguing for, we're in a whole new world of crazy. /1
As I said yesterday, we don't even have a "preemptive" nuclear strategy, which would be a shade faster than "launch on warning." "Preventive" strikes are a whole other animal. That's attacking your enemy because it's just a good day to do it. Like, Monday. Because why not. /2
As mathematician John Von Neumann said in the 50s: "If you say why not bomb them tomorrow, I say why not today? If you say today at 5 o'clock, I say why not 1 o' clock?" Take out your enemy as a child, as Don Ciccio says in Godfather II, before they grow up and seek revenge. /3

Okay. Those of you who want an explainer about why Elizabeth Warren's answer on #nuclear weapons wasn't crazy - and is basically a restatement of current U.S. policy - here it comes. Those of you who think Liz Cheney is right, I can't help you. /1
So, Warren said she would not use U.S. nuclear weapons preemptively. This is a word that's not as obvious as it seems. But to understand this, you need to understand "first use" and "first strike" and "no first use." That requires a quick trip back to the Cold War. /2
During the "missile age," post-1960, the question was: "When is it okay to fire your missiles in retaliation for an attack on yourself?" The problem is that if you go too soon, you might be jumping the gun on just a warning, but if you go too late...well, you're too late. /3

Today marks two years since the VC Summer #nuclear construction project was suddenly abandoned, quickly becoming one of the largest financial, legal, political and regulatory debacles in the history of South Carolina. Thread (1/?):
A quick search of @thestate's archives show we have since published more than 500 stories, editorials, op-eds, and letters to the editor about VC Summer. I've spent the past two years following the story, with tons of help from @sfretwell83 and others here.
We interviewed sources and reviewed hundreds of thousands of documents to piece together how the project failed, who enabled it and benefited from it and how it had caused the power bills of millions of #SC residents to soar. A few highlights:

I can see we need a “no first use” #nuclear explanation. Because Warren was right. So, heads up, #expert explainer incoming. /1
The United States does not reserve a first use option because of a possible attack on the United States. That misunderstands where all this came from. It comes from being conventionally outnumbered by the Soviet Union 40 years ago. /2
NATO warned the USSR that conventionally overwhelming us in Europe, which they could do easily, could trigger a nuclear escalation, and eventually a central nuclear exchange. Basically, we said we will do it if we are losing. /3

What does the IPCC say about #nuclear energy? ☢️
In this thread, I will try to summarize in a simple, complete and objective way ALL the points risen by the @IPCC_CH 🇺🇳 about this #energy source in its latest report: “Global Warming of 1.5ºC”🌍 Surprises are assured...👇🏽
Let's start with some background. Why do we talk about 1.5?
In the Paris Agreement at the end of 2015, 195 countries agreed to hold the average temperature increase below 2°C and to make efforts to limit it to 1.5°C. It was a major diplomatic and environmental achievement. 🎆👏🏽
The IPCC was asked for a report on the effects of global warming of 1.5°C and the possible pathways that would avoid exceeding this threshold. The effort was huge: 224 authors reviewed more than 6,000 scientific articles and more than 42,000 comments from expert reviewers.

(MBS = Mohamed Bin Salman, leader of Saoudi Arabia)

Report on Nuclear Reactor Lobby
by Committee on Oversight and Reform
Chairman: Rep. Elijah Cummings
Corporate interests of specific companies are more than legally allowed influencing US Security Policy.
Think of: selling NUCLEAR REACTORS to Saudi Arabia (about 30), passing by non-proliferation concerns.
Also passing by PUBLIC DEBATE (aswellas fair chances of rival companies).
Officials of ONE COMPANY, named IP3, had unprecedented access to key figures around and including the president.
Tom Barrack (direct friend of Trump) played a key role as a liaison (most likely a paid one). This going on from the inauguration, which is more than 2 years ago.

Cameco $CCO $CCJ Conference Call is now over. Here are a few tidbits:
Purchases have increased to 21-23M lbs #uranium for 2019 calendar year. 12.7M lbs committed purchases so far. Will also begin purchasing for 2020 needs later this year. 70% of buying will be in Spot market...
Increase of 2M lbs in contracts was due to clients wishing to add some lbs to existing deliveries. Off-market discussions increasing with utilities on term contracting. Definite rise in #nuclear utility interest since 232 removed border trade issue...
Cameco says still lot of undisciplined producers/sellers in both Spot and Term markets keeping prices from recovering, but volumes of material dropping. Also took a shot at developers who are promising to bring on supply even tho unrealistic at current prices, not helping...

Here we go again on new #nuclear power...

Last night, when most sensible people were having an evening's rest, a shambolic piece of policy was published…
Here's the critical para

And that's all you're going to get as justification for major energy system choices, which will cost billions of ££ and commit UK to infrastructure legacy for decades

(in fact given nuke waste, hundreds of thousands of years)
What's being proposed is best explained here - the only coverage I see of this government paper this morning

The point of these proposals is to make it easier for investors to build #nuclear by throwing lots of risk onto the energy bill payer…

In my confidential report commissioned by the Governor of #Ohio, Dick Celeste, I warned that Ohio #nuclear plants would impoverish bill payers and cause industry to flee the state. The year was 1985. And so it went.… #Environment #GreenEnergy #Pollution
This week, the #Ohio GOP toadies to the power industry will try to pass another billion dollar bailout to throw down the radioactive rathole. Three decades of bankrupting #nuclear plant operation in the shadow of #Fukushima shows the politicos have gone from dumb to dumber.
And for those who believe #nuclear energy is green & clean, I invite you to visit uranium mines in Niger, the Congo, and the Acoma pueblo in New Mexico. The only thing green about nuclear power is the plume of dollars flying out the cooling towers!…
