- However, a low energy beta will have great difficulty leaving the bulb,
- let alone passing through the lampshade, the air, or your clothes. CF

- Yep, I feel the same way when I am driving my licensed vehicle at or

- Good idea. But do not stop there. Suggest that they put a bottle of
- GatorAde (sorry you folks at UF, any of the "replacement" sport drinks)
- next to it. <quite a nice effect, BTW> Compare to CF bulb. Look for
- any warning label on the respective packages. A learning experience!
- Also might compare to a banana and your own body.

- Naturally ocurring radioactive materials do not have to be on labels
- if they are a natural part of the product -- even if concentrated
- during the processing of the natural food product. This is because
- the body will have a certain amount of potassium regardless of its
- source in your diet, and all potassium is radioactive. If there is
- no threshold effect, being too close to someone else would have to be
- considered a cause of cancer, and sex and subways would be banned.
