Course Description

Introduces biological effects of ionizing radiation and application of principles to minimize the risks of man-made radiation. Examines standards and requirements determined by government guidelines. Department permission required. Prerequisites: RAD 106.

Addendum to Course Description

This course presents a survey of the biological effects of radiation with emphasis on humans as the foundation on which protection practices are built. The student will study what makes radiation hazardous and the quantities that produce various biologic effects. Other topics to study will include safe radiation exposure levels for the general population and radiation workers, the basic philosophy of radiation protection, and how to practice radiation protection.
Radiation Protection and Biology is required as part of the Radiologic Technology degree program. It is also a prerequisite for taking the American Registry of Radiologic Technologists examination for certification in Radiography. Transferability of credit depends entirely upon the institution to which the student wishes to transfer.

Intended Outcomes for the course

Upon completion of this course, with a C grade or higher, the student should be able to do the following:

  1. Practice radiation protection for patients, personnel and the general public as well as understand the current radiation standards and guidelines.
  2. Analyze dose and biological effects of radiation exposure in medical radiography.
