Becoming a Radiation Worker


 

In order to handle Radioactive Materials on Mizzou's campus, each individual must become an approved Radiation Worker (RW). A Radiation Worker is an individual trained in radiation safety that is approved to work under the authorization of an AU with radioactive material without direct supervision. The AU is responsible for each RW and their acts of commission or omission who are approved to work under the authorization. A RW may work under more than one authorization at a time, but must be approved by each AU.

There are various types of RWs that require different training courses. Are you going to be performing:

Additional information on this page related to becoming a Radiation Worker or maintaining Radiation Worker status include:

Note: If you are only planning on using radiation generating machines, you do not need to become a RW. However, you will need to complete EHS 460 Radiation Generating Machine Safety Training for Research Uses which can be found on the Radiation Safety Online Training page. If you need dosimetry, fill out the Dosimetry Application found under the Rad Forms link to the right. You can find additional instructions on filling out the Dosimetry Application on the Monitoring Internal and External Exposure page. Contact EHS at rad@missouri.edu if additional assistance in assessing the need for dosimetry is required.

How to Fill Out the Radiation Worker Application

  • The RW shall complete sections 1-15.
    • Item 11: Indicate the formal radiation safety training courses that you have taken and/or attended. This includes the location, contact hours, and the date. For example, if you take the online training courses, write out the course title and length of course.
    • Item 12: Indicate actual, on the job experience with handling isotopes. If you have none, indicate so.
    • Item 13: List isotopes and activities you are expecting to handle. If you are unsure, contact your AU. This helps EHS assess your dosimetry needs more accurately.
    • Item 14: To be registered as a RW, you must indicate that you have received authorization-specific training from the AU or their staff covering radiation safety, laboratory safety, and your worker responsibilities. Be sure to include the dates of the training. See the Training Guide for Radiation Workers under the Rad Forms link to the right for training topics that should be covered.
    • Item 15: All applicants must read the responsibilities statement and then sign and date the form.
  • The Authorized User shall review sections 1-15, agree to the responsibilities statement, and approve this application by signing/dating section 16. The application is not valid without the AU signature.
  • Submit a signed and completed copy to EHS at rad@missouri.edu or email a copy to your assigned HP.
  • EHS will assess the need for dosimetry. Do not fill out the bottom section.
  • If dosimetry is needed, complete the Dosimetry Application found under Rad Forms to the right. For help filling out the forms, see the Monitoring Internal and External Exposure page. If you know prior to submitting the Radiation Worker Application that you will need dosimetry, the form can be filled out and submitted to EHS at the same time as the Radiation Worker Application. Allow approximately one week for dosimetry to be ordered and received.

 

Refresher Training Information

RWs working in research laboratory or veterinary medicine clinical settings are required to complete radiation safety refresher training once every three years. RWs working in a clincal setting with humans must complete refresher training once every year.

  • If you are a RW in a research laboratory setting, go to the Radiation Safety Online Training page and complete the course EHS 410 Radiation Safety Refresher. Refresher training is required every 3 years.
  • If you are a RW in a veterinary medicine clincical setting, go to the Radiation Safety Online Training page and complete the course EHS 413 Veterinary Medicine Radiation Safety Refresher. Refresher training is required every 3 years.
  • If you are a RW in a human clinical setting, please complete the same exact courses that were initially required unless your job duties have changed. Course options for RWs in a clinical setting with humans can be found in the RW performing clinical work with humans section. Medical radiation safety training refresher is required annually.

 

Removal of Radiation Workers

When a RW is no longer working under an authorization, please contact your assigned HP  to have that individual’s registration closed out for that authorization. Be sure to indicate if dosimetry should be cancelled also. You can also request to remove an individual through EHSA. See the tutorial video "Add/Edit Worker to a Permit" on the Tutorials page for assistance.

 

Importing Large Number of Radiation Workers into EHSA

If you have a large number of workers (>10) that need to be added to EHSA so that training can be accessed, email rad@missouri.edu to obtain a copy of the spreadsheet import file. When filling out the spreadsheet,

  • Make sure that every cell is filled out properly. Submissions will be rejected if the spreadsheet is not filled out correctly.
  • Pawprint needs to be the University assigned pawprint, not the alias. Using a worker's alias will further delay their access to training.
  • If adding the workers for the first time to EHSA, then the PI will need to be the "Radiation Safety, Training" RAM permit. If all workers have completed training already and need to be directly added to their Authorized User, then specify the Authorized User under the "PI Name" column.
  • Worker Function must be selected. A worker function determines a worker's training course. See the Radiation Safety Training page for a description of each available worker function. 

This spreadsheet can also be used to remove a large number of workers from a RAM permit. Fill it out in the same manner as adding workers. Submit all spreadsheets to your assigned Health Physicist or rad@missouri.edu.
