The deadline to submit entries to the 2013 Nevada radon poster contest has been extended to Oct. 30.

It is open to all children ages 9-14 who are enrolled in a public, private, territorial, tribal, Department of Defense, and home school. Children can also enter through a sponsoring club, such as an art, computer, reading, science, scouting organization, or 4-H club. Entries are free, but are limited to one per child.

Posters should follow these five topics: 1) What is radon? 2) Where does radon come from? 3) How does radon get into our homes? 4) Radon can cause lung cancer, and 4) Test your home for radon.
