ASRT publishes two journals that may be appropriate places to publish your work: Radiologic Technology and Radiation Therapist.
From the ASRT website:
"Radiologic Technology is published six times per year. The journal focuses on all aspects of medical imaging and radiologic technology practice, including education and radiology administration. Articles cover specific diagnostic imaging techniques, anatomy, disease processes, patient positioning, equipment protocols, radiation safety, radiation protection and basic patient care."
"Radiation Therapist is published two times per year. The journal covers all aspects of radiation therapy practice, including education and radiation oncology management. Articles cover specific radiation therapy techniques, anatomy, disease processes, patient positioning, equipment protocols, radiation safety, radiation protection and basic patient care."
Journal guidelines can be found attached. This file is one of the most IMPORTANT documents to use while revising your paper into an article. These guidelines tell you how exactly to format each section, what each section should contain, and which section of the journal may be most appropriate for publishing your topic. Read it first.
If you would like to look for other journals, you can use Scimago journal rankings to identify different academic journals in your field, and also get a brief indication of how visible that journal is to other researchers and practitioners.
The paper you have written in class can likely be published as a literature review article. Typically, your paper cannot be submitted "as-is." When revising your paper, you'll want to re-read each section from a different perspective.
The last point, what questions might they ask while reading this, is where you can start to revise your document. You will likely need to add sources, create a more specific thesis statement, provide a broader discussion, etc.
If you want to expand your paper to include original research, or want to begin your own research project, there are a lot of supports in place to help you out. A notable one is the ASRT New Research Grant.
The ASRT New Research Grant page has additional information that include steps needed to authorize your research project. Part of this is to ensure that research is done in an ethical manner. TCC has its own Institutional Review Board (IRB) that must approve most research that involves people (or animals). You can view their website to see more about their process of approval. This often includes completing an online research ethics course.
