Tiny Atoms…Big Science introduces students to nuclear science and some of the specialized technologies researchers use to study radioactive materials, detect radiation, and explore nuclear energy.
Through interactive experiences inspired by research at Oak Ridge National Laboratory, students discover how scientists and other STEM professionals work with materials and technologies that have applications in human health, energy, scientific research, and national needs.
What You’ll Do in the Exhibit
Students explore nuclear science through interactive activities that demonstrate how researchers work with radioactive materials, detect radiation, and investigate nuclear technologies.
In the exhibit, students can:
Learn about technologies used in fusion research.
Use remote robotic manipulators to move simulated radioactive materials.
Explore specialized radiation detection equipment.
Investigate how technology can help scientists work safely with radioactive materials.
Learn about ORNL research and technologies related to nuclear energy.
Explore how centrifuges can be used to separate isotopes and other materials.
Explore Nuclear Science
Nuclear science involves studying atoms, their nuclei, and the processes that can change them. While nuclear science is often associated with power generation and national security, its applications extend into areas such as human health, energy, and scientific research.
ORNL researchers use nuclear science and specialized technologies to investigate materials, develop new capabilities, and advance research with applications important to the nation.
Working Safely With Radioactive Materials
Some radioactive materials require specialized equipment and facilities so researchers can work with them safely.
Remote robotic manipulators allow trained operators to handle highly radioactive or radioactively contaminated objects without directly touching them.
In the exhibit, students use remote robotic “hands” to move simulated radioactive blocks inside a research hot cell. The activity introduces students to some of the tools researchers use when working with materials that require additional protection and careful handling.
Detecting Radiation
Detecting and measuring radiation is important in scientific research and in protecting workers and the public.
Different types of equipment are designed to detect radiation in different situations. In the exhibit, students explore examples of radiation detection technology, including handheld detectors and simulated roadside detection equipment.
The experience introduces students to how specialized instruments can help identify and measure radiation.
Explore Nuclear Energy Technologies
ORNL researchers investigate technologies that can contribute to advances in nuclear energy.
In this part of the exhibit, students learn about examples of research and technology associated with nuclear reactors, including the use of advanced manufacturing.
Students can also explore technology associated with fusion research, including a pellet injector designed to send cryogenic pellets into a fusion plasma.
Separating Isotopes
Scientists use specialized technologies to separate isotopes and other materials for research and other applications.
The exhibit introduces students to the concept of centrifuge separation. A spinning centrifuge can separate materials based on differences in their properties—an idea illustrated in the exhibit through comparison with processes used to separate cream from milk.
Explore STEM Careers
Nuclear science depends on people with a wide range of scientific, engineering, technical, and safety expertise.
Through the exhibit, students encounter examples of work involving radiation detection, remote handling technologies, nuclear energy research, advanced manufacturing, fusion technology, and isotope science.
These experiences help students see how specialized instruments, technical skills, safety practices, and scientific research come together—and introduce them to the variety of STEM pathways that contribute to nuclear science.
