The Third Annual Thomas S. Tenforde Topical Lecture HPS Ask the Experts: The Most Intriguing Questions and Answers.

The Health Physics Society (HPS) conceived of the idea of an online "Ask the Experts" (ATE) feature in 1999 when the Society created its website. ATE features are popular now, but at that time it was a novel idea, so there was no assurance it would succeed. Now 20 y later, the HPS considers its ATE feature a success and the most valuable service the Society offers for the public.

ATE evolution: becoming your resource.

The Health Physics Society (HPS) Web site was created in 1996 to further the HPS mission of promoting communication among people who conduct radiation safety activities; to encourage scientific, professional, and public education; and to disseminate sound scientific information. In 1999, a new feature called "Ask the Experts" (ATE) was added allowing individuals from around the world to pose questions concerning radiological protection. With the help of four editors, 20 topic editors, and 125 subject experts, nearly 5,000 questions have been answered.
