Radiation seminar Thursday at PCC


Wednesday, March 29, 2000

Radiation and the dangers it poses is the topic of a free seminar Thursday at Paducah Community College.

"Radiation and the Risks" will be presented by Ray Johnson, president of the national Health Physics Society. He is a former radiation expert with the U.S. Environmental Protection Agency.

The seminar will take place at 6 p.m. in Room 101 of Crounse Hall.

Johnson will answer the following questions:

--What type of radiation is safe and how much?

--Where is radioactive material?

--How is it contained?

--How can it move through the environment?

--What are the exposure conditions?

--How much radiation energy is deposited in the body?

--What is the risk of that radiation dose?

"These risks from radiation are not easy to understand because radiation cannot be seen, felt, heard, smelled or tasted," Johnson said. "Therefore, radiation is often viewed as mysterious, as a source of unknown danger."
