Cobalt 60

Cobalt-60 (60Co) is a synthetic radioactive isotope of cobalt with a half-life of 5.2714 years.: 39  It is produced artificially in nuclear reactors. Deliberate industrial production depends on neutron activation of bulk samples of the monoisotopic and mononuclidic cobalt isotope 59Co. Measurable quantities are also produced as a by-product of typical nuclear power plant operation and may be detected externally when leaks occur. In the latter case (in the absence of added cobalt) the incidentally produced 60Co is largely the result of multiple stages of neutron activation of iron isotopes in the reactor's steel structures via the creation of its 59Co precursor. The simplest case of the latter would result from the activation of 58Fe. 60Co undergoes beta decay… more »

In the valley with no mountain where a river hides
It's all quiet it's all silent wet and fresh after the rain
In the woods where I know every leaf every thorn
Where I saw in her eyes all the shades of the dawn
Here I am in the glade where the grass was so tender
Here she comes in the haze hovering among the trees
In the valley with no mountain where a river hides
At this time of the year life is at work once again
Swarming on every rock sweeping in under the green
Welling up from the ground as soon as it gets warmer
In the valley with no mountain where a river hides
The river there below / Quiet and gentle making no sound
The river where she drowned / Where her body could never be found
When I'm as quiet as I must be she strikes up a song for me
With her voice crystal clear a song no one else can hear
In the valley with no mountain where death took her life
Every leaf every reed spreads her song into the woods
She's so close she's so far and my heart is beating low
Something make me want to join her in her sleep I cannot share
In the valley with no mountain where a river hides(X2)
The river there below / Quiet and gentle making no sound
The river where she drowned / Where her body will never be found
