Determining the Source of Stream Toxins with Continuous Monitoring

Determining Stream Toxins with Water Quality and Level Data When researcher Wesley Gerrin gained access to a sediment toxicity lab in the Experimental Forest on the University of Georgia campus, he wanted to investigate an on-campus lake for any potential contamination issues. After his research was completed, he was fortunate enough to have some extra grant funding for the addition of a few samples from any location on campus, so he chose one of the most exciting sites on the University premises: Tanyard Branch. As Wesley said, “We ran the tests, and everything looked good, except for Tanyard Branch.” Tanyard Branch has been one of the most heavily monitored creeks in the Athens-Clarke County area for the last couple of decades due to contamination - it has a long history of abuse beginning in the 1700s. Native Americans long used the area as hunting and fishing grounds, but it was eventually seized by colonists. The people who then settled into the area opened botanical gardens - thi

North Carolina Radiation Protection Acquires Drone for Radiation Measurement

From left, Robert Goldstein of US Nuclear Corp , Lee Cox, Radiation Protection section chief and William Jeffries, Radiation Protection’s nuclear plant emergency response coordinator, adjust radiation detection sensors during the first day of drone training.      June 25, 2018  - After hours of tweaking the unit after assembly, North Carolina Radiation Protection’s drone was finally ready for its first test flight. “Everybody clear?” With a sound like a very large insect, the 45-pound drone took off, stirring up the corn leaves in the field below, culminating three years of work by Lee Cox and staff at the Radiation Protection Section to make this resource a reality.  The section, part of DHHS’ Division of Health Service Regulation, purchased the drone to send into potentially radioactive environments to collect data so human inspectors can remain a safe distance away.  North Carolina will be the first in the nation to use a drone for radiation detection. Other states are monitoring th

Is Radioactive Hydrogen in Drinking Water a Cancer Threat?

The EPA plans to reevaluate standards for tritium in water : Add two additional neutrons to the lightest component and hydrogen gets radioactive, procuring the name tritium. Indeed, even before the Three Mile Island mishap in 1979 controllers stressed that this omnipresent side-effect of atomic reactors could represent a danger to human wellbeing. The U.S. Natural Protection Agency (EPA) was just seven years of age when it put the main principles on the books for tritium in 1977. Yet, a ton has occurred in the mediating many years, and it's difficult a more drawn out rundown of atomic mishaps.  The Chernobyl and Fukushima emergencies let free a lot of tritium, however so have an apparently perpetual series of breaks at maturing reactors in the U.S. what's more, somewhere else. Such holes have incited the EPA to report on February 4 intends to return to norms for tritium that has discovered its direction into water—purported tritiated water, or HTO—alongside hazard limits for si
