Ask
a Question
Before you begin, please take a moment to read some answers to other questions to be sure yours hasn't already been asked. You can then ask a CHP your question about radiation or radioactivity by simply pressing the red button that appears at the bottom of this page. You'll have your answer just as soon as possible . . . but definitely within 10 business days! Try to frame your question as completely as you can. And please let us know if you would rather not have your question (and the CHP's response) posted.
Keep in mind that the answer given to you by one of our CHPs will be as accurate and defensible as possible in light of the content, form, context and assumptions presented in the question, and that the response given may not be universally applicable. As always, however, a discussion with a radiation protection professional is warranted prior to acting on any response.
