Radiation 101: What It Is, Why It's Dangerous

As radiation dangers related to Japan's damaged Fukushima nuclear power plant continue to make national headlines, many people are left wondering exactly what radiation is --and how exposure to it, in high doses, impacts human health. To learn more, we tapped radiation biologist Dr. Jacqueline Williams for a brief physics lesson.

I built special weapons from 1971-1974 in the Army and have radiation burns and sores from radiation exposure. My DNA was changed. The military does not recognize effects from radiation when I served so I am trying to become the first to change their rules.

She explained it to us like we are all dumb assess.... which we are.

Alpha= “A”ll right. Beta = “B”e careful. Gamma and X-ray= “G”et away and “X”it immediately.!! A good rule of thumb!

[John-...]

Finally! Very well explained. It only took about an hour of watching different YouTube videos to get an overall simplified explanation for me to put it all together. Most videos give a good explanation on one area but leave something out

Thank you for this. It was difficult to find a video on this subject which features someone who is educated in the subject. So many clickbait "armchair" science videos on Youtube.

THANK YOU! This actually makes so much sense and helps me understand. Very very helpful

Here because of the HBO show “chernoble”

Wow... I'm learning radiation and a physics from a Doctor. I'm loving this. My brain is open.

[VegetaUnv]

Haha im glad im not the only one. Every video of trying to find out what radiation is would turn into a physics lesson .

Clear madam. Thanks. Straight to the point.

Radioactive cigarettes, Now I know smoking is hazardous to your health and why I don’t smoke!!

[zoecanizares]

How come positive energy does damage to your cells?

[skipsassy]

tell that to the Chernobyl graphite radiation that kills in minutes a slow agonizing

[zypheralexander]

What about fire alarm systems in close proximity.people are getting sick all around us

[MrDometheo]

SUPERB!!!! 🤗 If i may, though?
Broadly speaking....:
1889, Power line harmonic radiation. Supression of Earths natural magnetic field.
1918, radio era began. Powerfull LF and VLF frequencies pumped out to magnetosphere. 1918, Spanish influenza.
1957, the radar era. Hundres of powerful military early warning stations littered high altitude latitudes of northen hemisphere. Milions of microwave energy surged skyward. Asian flue of 1957.
1968, satellite era began. Hundreds launched. Although, they had weak broadcast power, but compounded the already existing radio wave pollution in the magnetosphere. Hong Kong flue of 1968.

Next, Haarp activation and the beguining of the wireless era, cell phones included (4g and 5g etc)

Result?

Porphyrins and the Basis of Life...

Marconi, the idiot savant, learned his lesson quickly (or did he🤔😔) about the dire effects of eletromagnetic radiation and its interaction/disturbance within Human Self Organising Biology(and other animals/insects. Bees specialy!)...because dear reader, for the great luck ( or curse)of the indewling Life aspect, incarnating within the Biologicaly Self Organising presets of Inception, these Bioverses are, after all, responsible for automating of processes...Self Organisation fractals no less!! Let that, sink in!

Pregnancies being THE best example.
Or does the reader think thats it the mother (of ANY species) that assembles their pristine, profound, Highly Complex, offsprings....??? 🤔🤔🤔 indeed...

Such hubris does our species have, that incarnating life awhereness in symbiosis with these Self Organising Bioverses, that it goes on destroying it all!!! 😔😔😔
I mean the military not ""Global Warming"" (it should not take an advanced human being to perceive that it is the SUN, that does it all. RA)
That military fiat currency is best used for the emancipation of the Human race..but of years of stupidity culminate in some curious choices🤔 and genetic predispositions🤔 Free Will indeed...

How very advanced this present reiteration of incarnating humanity upon this Yuga is🤔. Greatly advanced🤔😂😂😂
I do believe i have seen more inteligent potential sentience in Cats( despite their neural interfaces not allowing them to aproach human biology IQ levels) then in our "species"🤔...Very much so..🤔

I just wanna know if I can listen to my AirPods

@TheaDragonSpirit oh shush that's not the point

[filteredview]

Her explanation in the end is a bit scuffed, and it probably isn't easy for anyone new to radiation to understand what she said correctly.

The title would be better if it were named "Radiation 101: What It Is, Why It isn't Dangerous"

Because radiation is only dangerous when in very high amounts... yes radiation is dangerous but so is water. if you drink 10 liters of water you die, if your exposed to 0.1mSv with x-rays in 2 seconds. (Ct scan) you're fine. which are a ton of particles btw! 0.5mSV/s is the equivalent of holding a source that is "180 mSv/h" expect it isn't because it isn't even a full body dose.




my point is to draw you away from the idea that "one single radiation particle" from a radioactive element can cause any harm, or genetic defects because it can't. 1 particle only effect one atom, and that's it. radiation happens at a very tiny level, I have radioactive sources that are considered safe, but reads upwards to 600uSv/h. which range from 350000bq (atoms decaying every seconds) which is no problem to have around, because the activity is simply not enough to do any harm., Billions of atoms every second or
3 000 000 000 bq, then it's dangerous! people who die are exposed to billions of atoms in total,

So if we compary radiation to other things that are more dangerous such as poison, then it's totally safe within itself, until a certain point if that makes sense, water is also safe until you drink too much, but isn't dangerous if you drink small amounts. same with radiation

thanks for reading, hope this can make an interesting conversation.

Aren't you Scopus to use the word energy then radiation
