So, I'm gonna pull out pictures, ones with you in 'em Laugh and cry a little while reminiscing
By myself
I can't help
That all I think about is
How you were taken way too soon
It ain't the same here without you
I gotta say, missing you comes in waves
And tonight I'm drowning

And one day I'll see you again
But it's killing me we can't be face to face
I miss my best friend

so the answer would be radiation.
