• OverExposed: A Biologic Look at Radiation Incidents

Discover the captivating world of radiation incidents in our online course, "OverExposed: A Biologic Look at Radiation Incidents." Led by the knowledgeable and engaging instructor Cybil Nielsen, this course will empower you with practical skills and essential knowledge that will elevate your expertise as a radiologic technologist.

In just 3 hours (150 minutes) of engaging content, you'll embark on a fascinating journey through the history of radiobiology and the impact of radiation incidents since 1896. Delve into the intricacies of radiation types, wavelengths, and frequencies, uncovering their profound effects on biological systems. Through real-life case studies, including radiation poisoning incidents and the victims of atomic bombs, you'll gain a deeper understanding of the consequences of high radiation doses.

Explore the measurement of radiation exposure, absorbed dose, equivalent dose, and effective dose, equipping you with the ability to assess the potential risks and benefits. Immerse yourself in a biologic examination of human composition, examining the distinction between fractionated and protracted radiation exposure. Uncover the vital concept of ALARA (As Low As Reasonably Achievable) and its foundation on the linear, no-threshold model.

By the end of this course, you'll have the confidence to define critical terms related to radiation dosimetry, evaluate the effects of radiation on various bodily systems, and comprehend the distinction between deterministic and stochastic effects. You'll be able to assess radiation exposure in different imaging procedures and make informed decisions to minimize patient risks.
