Summary
The Environmental Protection Agency limits public radiation dose from U.S. Department of Energy facilities to 0.1 mSv annually. New databases track unmonitored radionuclide emissions at Oak Ridge National Laboratory to ensure compliance with National Emission Standards for Hazardous Air Pollutants.
Area of Science:
- Environmental Science
- Radiation Protection
- Regulatory Compliance
Background:
- U.S. Environmental Protection Agency (EPA) established emission standards for radionuclides under 40 CFR 61, Subpart H.
- The annual effective dose limit for the public from Department of Energy (DOE) facilities is 0.1 mSv.
- All DOE facilities on the Oak Ridge Reservation must collectively meet this 0.1 mSv annual dose limit.
Purpose of the Study:
- To maintain radiological source and inventory information for unmonitored emission sources at Oak Ridge National Laboratory (ORNL).
- To support the annual Radionuclide National Emission Standards for Hazardous Air Pollutants (Rad NESHAPs) report required by 40 CFR 61.94.
- To provide supporting documentation for facility compliance audits and track doses for Oak Ridge Reservation facilities.
Main Methods:
- Development of the Environmental Protection Rad NESHAPs Inventory Web Database to manage data for unmonitored sources.
- Annual updates to the inventory database for emissions data compilation.
- Development of a Rad NESHAPs source and dose database to import data from Clean Air Act Assessment Package-1988 (CAAP-88) model files.
Main Results:
- The developed databases maintain comprehensive radiological source and inventory information.
- Emissions data is compiled for the annual Rad NESHAPs report, ensuring regulatory compliance.
- Facility-specific and Oak Ridge Reservation-wide source inventories and associated doses are tracked.
Conclusions:
- The databases are essential tools for managing unmonitored radiological sources at ORNL.
- These systems facilitate accurate reporting and compliance with national emission standards for hazardous air pollutants.
- Comprehensive dose tracking ensures adherence to the 0.1 mSv annual effective dose limit for the public.

12.6K
Many heavier elements with smaller binding energies per nucleon can decompose into more stable elements that have intermediate mass numbers and larger binding energies per nucleon—that is, mass numbers and binding energies per nucleon that are closer to the “peak” of the binding energy graph near 56. Sometimes neutrons are also produced. This decomposition of a large nucleus into smaller pieces is called fission. The breaking is rather random with the formation of a large...

Radioactivity is a spontaneous disintegration of an unstable nuclide and is a random process, as all the nuclei in the sample do not decay simultaneously. The number of disintegrations per unit time is called the activity (A), which is directly proportional to the number of nuclei in the sample. The decay constant (λ) is an average probability of decay per nucleus in unit time.

Nuclear chemistry is the study of reactions that involve changes in nuclear structure. The nucleus of an atom is composed of protons and, except for hydrogen, neutrons. The number of protons in the nucleus is called the atomic number (Z) of the element, and the sum of the number of protons and the number of neutrons is the mass number (A). Atoms with the same atomic number but different mass numbers are isotopes of the same element.

Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

Controlled nuclear fission reactions are used to generate electricity. Any nuclear reactor that produces power via the fission of uranium or plutonium by bombardment with neutrons has six components: nuclear fuel consisting of fissionable material, a nuclear moderator, a neutron source, control rods, reactor coolant, and a shield and containment system.
Nuclear Fuels
Nuclear fuel consists of a fissile isotope, such as uranium-235, which must be present in sufficient quantity to provide a...

All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...
