Anyone know the Royal Institution lecture this was taken from, I'd like to see the whole thing?

[@pranavratna]

What was the simulation he used to demonstrate the pet LOR ? How was it made visible.

[@lukaszha8826]

1:07 gamma rays. X rays are rays released by orbital electron transmissions not nuclear activities.

[@atlaskat7980]

Okay but doesn't the antimatter annihilations happen wherever the positron hits an electron? How does it work then, that we can see the cancer specifically? How is are the annihilations different to one another?

Thanks sir

[@geovaniodabahia9886]

Muito bom, gostei da explicação, só faltou entender kkkkkkkkkkkkkk

[@tand9854]

He made a mistake. Should be gamma rays are produced. Not x rays.

[@gustavofoss2280]

They overlap in energy

Wow. Educated man can't pronounce "beta."

Not true. He is pronouncing the Greek letter in the right way (almost)

What an amazing insight, a person with a different accent to yours pronounces words differently from the way you do..

[@ThatOne77]

@@TheClumsyFairy I'm sure you're doing your best. Bless your heart.
