WASHINGTON — Radioactivity reaching the United States from the Chernobyl nuclear accident has declined so much that the Environmental Protection Agency said today it will stop reporting radioactivity concentrations at the end of this week.
The agency's daily report on behalf of the interagency task force monitoring Chernobyl developments said that only 12 out of 26 rain samples analyzed by EPA monitoring stations contained iodine-131 and average concentrations were continuing to fall.
