radioactivity explained

This video covers what radioactivity is, and in particular what alpha, beta and gamma emission is. I also cover the notation used to represent radioactive emission.

Now this a spectacular way to teach what radioactivity is . The systematic logic made it so interesting and easy to understand . thank you

Thanks

Just starting a degree in Radiotherapy. I don't understand this topic at all but I came across your video and has really helped me understand some stuff now. Love for the help and explanation

[@ritualj0int]

Good luck mate ✌️

Awesome video. Best I've seen so far 👏

well done! i always look forward to your videos :)

Amazing 👏 sucks it took me till I was 30 to gain an understanding on a topic "taught" to me in highschool

[@jxyoutube]

Great explanation! Radioactivity explained in simple way that anyone can understand it. Thanks!

You’re welcome

You made it so simple. Thanks!

Thanks bro you explanation is so simple

Hello sir In the alpha decay of uranium 238 the newly formed element is also short by 2 electrons. Where do these electrons go in the process? Regards M Jafar

[@MohammadAli-sg8bj]

thanks for the detailed video, the beta Particle that deflected, in the magnetic filed(will it be Beta minus or meta plus?)

He says at 21:30 that it’s “not a positron”

[@engineermerasmus2810]

Easy to understand, well I alredy knew this, but I think anyone can understand it!

[@ajitsinghjhala961]

very well explained thank you

[@yodustin00]

I have a question. How come all models of an atoms nucleus for the exceptions if a few very light particles like alphas, deuterium, & protium show the nucleus as a jumble mess kinda like a plum pudding model applied to the nucleus. I highly doubt that to be the case. I think it also explains way a helium nucleus is the standard alpha particle. What does the tritium nucleus really look like in a 3D model at what opposing angles are these baryons at in that case and does it scale. Is this the key to isotope stability?

Woah this was very helpful thank you so much for this video

You’re welcome

You should do an audiobook on this topic... this is all really fascinating

[@allolebarilliertaxi4304]

Thank you very much, i surely won't be able to remember all but now i understand a little bit better what are radiations. I guess i'll come back to strenghen what i learn today. So i will be a little bit able to explain this to my children.

[@PhysicsHigh]

You’re welcome

[@ognjen297]

Thank you for the video. I don't understand one thing, let's assume that we had atom with mass number of 3 and atom number of 2, and If we know that in the beta decay mass number stays the same and only atom number changes, does that mean that the nuclei of the atom will never get to the stable state and we will have indefinite decay ? (I am pretty sure that I am missing something)

[@Kingstanding23]

This video has been useful.

[@finnstadel]

Random and spontaneous. Orbits are not random, but I guess they are pushed around by the vacuum fluctuations causing random event like radioactive decays. But where does this seemingly randomnes of the vacuum fluctuations really come from ? Is it comparable to brownian motion or the noise from electrons jittering around in a conductor ?

If you define the word nuclei before starting your explanation, you will have tons of more people understanding and watching the whole video.

Thank you! My 7 year old asked about how the get electricity. Which led down a rabbit hole about nuclear energy.... radiation.... Chernobyl...

Trying to create a manga power system that focuses on radioactive powers so I’m doing a TON of research.

[@rafaylifts]

Why is lead stable and realeses almost no radiation when number of neutrons is much more than protons

[@j1n2]

That's really a good question. after watching this video I think of 2 possible options: 1) the amount of protons and neutrons in new Pb atom is just enough for a strong force to keep it together. 2) It may be actually unstable for the first time but then there is some type of a gamma decay after so that in the end Pb will become a low energy Pb and then it's point 1 again - strong force can keep it together. I wonder how close am I though ?

[@stevee.oneder891]

Because you’re not factoring in the electrons

[@5688gamble]

People fear radioactivity too much. You respect it, like anything else. I imagine that since radiation is everywhere, that our bodies probably even depend on it to some degree, generating radicals and ionizing stuff, so if we isolated them from radioisotopes completely, might cells actually do worse or even get quite sick or die? Too little could be bad, much as too much is!

[@phantom8845]

Cool but isnt it dangerous to hold uranium in hands if its that radioactive?

[@richardprichard7917]

does radiation explain why my left ear is hearing more than my right?

[@v.prestorpnrcrtlcrt2096]

Shhhh, Man speaking.

[@mesothelioma5024]

I don’t understand almost half of this but I love this kind of stuff

[@billybobhouse9559]

Great video. I don't understand why the radiation is dangerous though? Don't we already have protons and neutrons in our bodies already? Why do these particles cause harm? Thanks.

[@uramijajlovic5444]

Because the radiation can penatrate deep into our tissue, and cause harm to the very fragile DNA.material and lead to very bad mutations. It can cause, and as. we know of nowx it does cause cancerand overall is just very destabilizing for our body's natural way of functioning.

6:22 you drew your plot the wrong way around

[@hiddeemmen]

How am I the only person who noticed?

[@captainshipman7377]

I don’t see what’s wrong with the plot. It’s a graph of protons vs neutrons. For larger atoms, there tends to be more neutrons, so the graph will curve upward (since he has neutrons on the y-axis or vertical axis)

No way I’m watching a 25 minute video just to know what radioactive is, LIKE WHY CANT YOU MAKE A 1 MINUTE VIDEO AND SIMPLY SAY WHAT RADIOACTIVITY IS?!?
