Thanks for your help guys! This worked perfectly. I used print_r to display the field_energy array and noticed that the values are not stored with integer keys but rather with text keys. It turned out that I have to use $entity->field_energy['und'][0]['radioactivity_energy']. For some reason applying float() to this gives me an error though. But if I don't apply float() I can still use the value as a real number.

In addition, you can download/enable the [Devel Module] (drupal.org/project/devel) and call kpr() on your $node or $entity object. This is functionally the same as calling print_r, but provides a nicer output style.
