Ask the Experts
Do you have a question about radiation safety? Our 22 Ask the Experts (ATE) topic editors and more than 200 experts can help. If you are a member of the public or the media, a health physicist, or a scientist in a related field, you can either find the answer to your question or you can submit your question.
Nearly 12,000 questions have been submitted and personally answered by our experts. Many of these questions and answers are posted along with FAQs and information sheets under 28 different radiation safety categories.
Radiation is beneficial for medical diagnosis and therapy, scientific research, and generating electrical power. However, when used in unsafe ways, radiation can harm people. Care must be taken to properly use radiation and to minimize unnecessary radiation exposures.
Our radiation safety experts have the knowledge and experience to discuss with you the benefits and/or risks while answering your question.
Before you submit your question to us, we invite you to search through our list of answers to previous questions. Or, you might search for the answer to your question in our other posted materials.
If you have a radiation safety question that we have not already addressed, please submit it to us through our questions page. We do not answer questions that are not in the field of radiation safety. We also cannot provide medical advice and we do not answer homework questions.
We have an experienced editor in charge of each category (topic) in our field. When a question is submitted and it is appropriate for us to answer, this topic editor either answers the question or assigns it to an expert in that subject area. You always receive a personal email response to your question. If the topic editor decides your question is of general interest, it will be posted on our website (excluding your name). You can find out about our editors and see their photos on our Meet our Editors page.
We invite you to explore another website that we sponsor that is dedicated to public education. This site (www.radiationanswers.org) presents scientific and objective information about radiation in an easy-to-read format.
