WAVERLY, Ohio (WSAZ) -- UPDATE 5/13/19 @ 6:40 p.m.
A middle school has closed its doors after radioactive materials have been detected inside and outside of the school.
The Scioto Valley Local School District decided to close Zahns Corner Middle School after enriched uranium was detected inside of it.
This comes less than three weeks after another radioactive material, Neptunium 237, was detected by a U.S. Department of Energy air monitor located near the middle school.
In a letter to parents and staff, the Scioto Valley Local School District states that the middle school will remain closed "until the source, extent, level of contamination, and potential impacts to public health and the environment can be determined."
The letter also states that the enriched uranium and Neptunium are "contaminants of concern by the U.S. Department of Energy on the Portsmouth Gaseous Diffusion Plant property" which is located near the middle school.
The Scioto Valley Local Schools District says it worked with the Pike County Health Department to make this decision.
