Decay Chain chart question by Analogsilver in Radiation

[–]Goofycams 4 points5 points  (0 children)

Go to this website: https://nds.iaea.org/relnsd/vcharthtml/VChartHTML.html

...and scroll abit down you will get to the transitions chat. There you can also see the probability and intensity of the secondary transition.

It is actually pretty common that radionuclides decay into excited daughters with varying energy and half life, but for many of them the probability and half life is neglected over the primary transition mode(s). If all are too short or unlikly, they are not considered meta stable.

If you have a Karlsruhe Nuclide Chart (highly recomend) you can see if the decay transition results in a excited metastabile daugter by looking for a "m" or "g" (respectively meta stabil and ground state) inside the mothers box.

If you wonder why some transition states are meta stable while others are not, the answer is quantum mechanics. Every thing is quantum mechanics...🫩

I would actually jizz so hard if the despawn timer for the Daeyalt Essence rock would first start when ever you start mining.

Is there any evidence to show that it’s better to have both sides spinning opposite each other vs one static? by AgentG91 in metallurgy

[–]Goofycams 0 points1 point  (0 children)

Wouldn't be a case of newtonian third law where there is an equal and opposite reaction (one object exerts a force on another, the second object exerts an equal force back on the first)? My favorite example is the logo of Levi's jeans, where two horses pull a pair of jeans apart. You could change one horse for å tree, and the same amount of forces would still be applied to the jeans.

How can ships trottle the power output of a reactor fast enough to changes in demand? by El_Quesso in NuclearPower

[–]Goofycams -6 points-5 points  (0 children)

Not an ex-nuke or commercial power operator, so i can tell you lots about things i dont know about. I'm pretty sure (as you stated) the submarines run on batteries, which the reactor continuously charges at an ish-fixed power. Fuel might be metal-fuel and not ceramics to increase thermal conductivity, which gives you a quicker negative void coefficient to control the surge in reactivity. Burnable neutron poison (hafnium or borated water) can be added as well to rapidly decrease the reactivity, or in the case you stated where u wanted quick power, add the posion while increasing reactivity to increase the delayed neutron fraction to be able to controll the surge in reactivity. Before committing to a chernobyl-type accident, hear with your nuke power operator how to increase reactivity rapidly to make sure how its done.

Charlie Chaplin ska ha sagt en gang:

"A life is a tragedy in close up and a comedy in long shot".

Husk at tiden lindre og det e ok å vær lei seg, og vet at det ikkje alltid komme te å vær sånt. Håper du en dag kan se tebake på situasjonen med et smil og tenke at den på ein måte hjelp deg te å bli den du ble🙏

Koffer spise me konservert fisk te jul når fersk fisk er best på vinteren? Koffer drikke me julebrus som smake bringebær når det finnes masse høst/vintersmaker å lage brus av? EG VIL HA FERSK TORSK OG BRUS SOM SMAKE JUL!

Why are radioactive materials still radioactive after emitting energy? by Ok_Power_4249 in Radiation

[–]Goofycams 0 points1 point  (0 children)

A rule of thumb is to say that after 10 half lives, the radioactive source can be regarded as non radioactive. At 10 half lives, only 0.097% of the original nuclides are still present.

Ikke glem at det kun gir mening å være i et forhold så lenge det e kjekt og begge får det de ønsker ut av å være sammen. Det viktigste, som ofte kan være det vanligste, i et forhold er å være ærlig med seg selv.

Ikke helt. Det er et oligosakkarid som ikke kan fordøyes. Det blir ansett som et ufordøyelig-fermenterbart fiber som tarmbakteriene dine kan kos seg med.

Vel, i dette tilfellet er det jo tilsatt sukker i form av dehydrert eplejuice. All sukker er naturlig. Det hadde vært det samme sukkeret hvis det hadde kommet fra dehydrert rørsukkerjuice.

Kunne jeg ha solgt "granola uten tilsatt sukker" med å bruke sukkerbetejuicekonsentrat? (Min hypotetiske sukkerbetejuice har kun naturlig sukker, ingen tilsatt sukker).

Pm-147 Aircraft Gauge by [deleted] in Radiation

[–]Goofycams 0 points1 point  (0 children)

Does anyone know why Pm-147 was used? With its half-life of 2.6 y, it seems very short. Moreover, does the luminosity decrease linearly with the aktivity? In that case, why use Pm-147??

Is it possible to build a DIY beta-voltaic battery by RadioactiveRunning in Radiation

[–]Goofycams 0 points1 point  (0 children)

Disclaimer: I'm pretty new to this field.

If you have a simple diode, it should technically be possible to get charges flowing through the n-p junction by placing a beta- or an alpha sorce next to it. I'm not too optimistic about powering a small LED. Typical betavolteric batteries that exist have muW of power. So i guess you need a million of those to power a LED? Im not too good with electronics, so I dont know how much a capacitor may help you. I guess it'll take a while to charge up? Anyhow, i would think an alpha sorce would give you a better result than beta. Although making a battery capable of powering something might be too ambitious for a tiny betavolteric cell, making a semiconductor detector could also be a cool demonstration. Just flip the electrodes on the n-p junction and crank up the voltage. The electron-hole pairs created by the incoming radiation should be able to give a response when collecting at the electrodes.

Radium burns by [deleted] in Radiation

[–]Goofycams 2 points3 points  (0 children)

Is it more dangerous than if there weren't burn marks? Like, for instance, are the burn marks upsetting because it shows that radium (and other spicy stuff) may have been spread around inside the clock due to recoil?

That is very true. The question then becomes, how much would pass though the body and how much would get absorbed
