Programs established in 1970’s and 1980’s
Required for licensee
Preoperational and Operational
“check” on effluent releases (ODCM)
Verification of “pathways to man”
Established for Routine and Emergency Releases
![Page 3: Radiological Environmental Monitoring – Where We Are, Where We’re Going](https://reader036.vdocuments.mx/reader036/viewer/2022062803/56814802550346895db5341f/html5/thumbnails/3.jpg)
Primary Pathways of concern –
Releases via air (gas and particulates)
Releases via water (discharge effluent)
Typical Media –
Water – Surface, Drinking, Ground
Air – Particulates, Gas (primarily iodine)
Vegetation – leafy plants, edible products

Typical Media –
Milk (cow, goat, etc.)
Meat (grazing animals – cow, deer, bison, etc.)
Fish
Soil
Sediments
Oysters, shellfish

Determine early trends of environmental build-up (bio-accumulation/animal tissue) of rad material in environment
Measure primary and secondary routes of potential exposure that could have a negative (risk) impact to the general population
Mitigate impact to humans to achieve negligible risk

Nuclear Regulatory Commission Assess Licensee (on-going)
Fund “other” agencies to monitor environmental radiological impacts
State agencies
Private agencies (few)
Other federal agencies (FEMA)
![Page 7: Radiological Environmental Monitoring – Where We Are, Where We’re Going](https://reader036.vdocuments.mx/reader036/viewer/2022062803/56814802550346895db5341f/html5/thumbnails/7.jpg)
Programs did what they were supposed to – few issues
Nuclear Regulatory Commission ceases additional agency funding in 1998
Accountability shifts from investigative to self-identified
![Page 8: Radiological Environmental Monitoring – Where We Are, Where We’re Going](https://reader036.vdocuments.mx/reader036/viewer/2022062803/56814802550346895db5341f/html5/thumbnails/8.jpg)
All existing programs meet minimum regulatory requirements
1990’s saw reduction of many programs due to budget constraints and potential deregulation
Facilities aging and seeking license renewal
Areas around facilities have changed
Definition of risk has changed

Technological improvements
Lower detection limits
Improved analytical methods
Resource sharing – internet, web-based
Comfort with nuclear power production…….

Maintain a heightened sensitivity to controls of radioactive material
Green means more than CO2 free – all emissions
Look “hard” for possible problems
Leaking pipes
Washout/rainout/plate-out/building wake effects
New Issues with updated regulations, e.g. C-14
![Page 21: Radiological Environmental Monitoring – Where We Are, Where We’re Going](https://reader036.vdocuments.mx/reader036/viewer/2022062803/56814802550346895db5341f/html5/thumbnails/21.jpg)
Any radioactive material in the environment can be an issue…..
Risk is a matter of public perception, not biological consequence
Public perception affects development and future expansion
Don’t wait for regulation change to take action – evaluate program with potential consequence in mind

Communicate, Communicate, Communicate
Take the mystery out of the science – Examples:

Create relative risk relationships people can understand
There are times we just challenge others with our communication…….

Care
Be prepared to spend $$$ when there may be little technical but much political justification
Always be open and honest – trust is the name of the game
Never Take for granted that you have arrived….
