Requisition Id 7660


The Nuclear and Radiological Protection Division at the Oak Ridge National Laboratory (ORNL) seeks a Radiobioassay Lab Technician for the Dosimetry Services Group. This position will be responsible for performing benchtop radiochemical analyses on human urine and fecal specimens to determine the presence of extremely low levels of radioactivity that may indicate potential internal occupational dose to radiological workers. The analytical results are used to demonstrate compliance with the DOE approved ORNL Radiological Protection Program under Title 10 Code of Federal Regulations Part 835 and in accordance with the provisions in the DOE Laboratory Accreditation Program.


Major Duties/Responsibilities:

The Radiobioassay Lab Technician must perform a variety of precision laboratory analytical tasks in a safe and reliable manner in accordance with procedural, work controls, and applicable Federal regulatory requirements.


Primary responsibilities include any or all the following routine tasks:

  • Perform low-level radiochemical analyses of bioassay samples (primarily urine and fecal samples), which includes sample preparation, radiochemical separation, and source preparation (electrodeposition, filtration, etc.)
  • Participate in other laboratory activities such as data entry, data validation, segregation and disposal of waste, preparation of reagents, routine maintenance and cleaning activities, performing inventory of chemicals and supplies, and preparation of standards.
  • Retrieve bioassay samples from sample drop-off stations, maintaining chain-of-custody, and log in relevant information into a Laboratory Information Management System (LIMS).
  • Review analytical data for completeness and accuracy.
  • Work overtime and hours outside of normal schedule when requested (such as during incidents).
  • Fulfill and maintain all required training (site-wide and job-specific).


Basic (Required) Qualifications:

  • An Associate’s degree in chemistry or related science/technical field with at least two to four year experience working as an Analytical Lab Technician, or a Bachelor's degree in chemistry, chemical or environmental engineering, or related science/technical field.
  • Work will involve various physical requirements and certain working conditions and as such a post offer, pre-hire physical will be required.


Preferred Qualifications:

  • Familiarity with spreadsheets and database entry applications.
  • Ability to learn new processes and adapt to change.
  • Ability to process multiple samples through multiple stages at the same time (“multi-tasking”).
  • Demonstrated ability to work independently and in a team setting


This position will remain open for a minimum of 5 days after which it will close when a qualified candidate is identified and/or hired.
