Collection of rainfall is an unsophisticated process involving a basin which drains into a collection bucket. A technician makes sure the basin and bucket are kept clean and picks up the samples as they accumulate. The EPA checks samples for radiation and acidity. Monitoring Radiation Particles in the air also contain levels of radioactive radiation which need to be monitored. The radiation sampler at Tillman works similar to the TSP sampler.
Air is drawn in at the top of the unit.
The air flow passes through a circular filter at the base of the head. These filters are collected periodically. After allowing the radioactivity to decay for five hours, the filter is placed inside a special Geiger counter. Send your questions and comments to the Webmaster at our site.
