'MRI training at Holmes Regional Hospital' - extracurricular activities

Please briefly elaborate on one of your extracurricular activities or work experiences in the space below (1000 character maximum).
I wasn't sure what they meant on the common application could you tell me if I am on the right track?

One of my extracurricular activities that i participated in was the MRI training at Holmes Regional Hospital. This different radiologic modality was not a part of any of my regular courses at Keiser University, but I was immediately drawn to it because of it's alien nature. During my externship, I decided to join this program at the hospital and I learned many new things that weren't taught to me in class. MRI, or magnetic resonance imaging, does not require radiation to work but magnets instead. MRI's, although very expensive, provide a better image than any other radiation modality for the visualization of organs and blood vessels. I completely fell in love with all of the machines and the different people working there and learned many of the safety measures when coming in contact with the magnets of the MRI machine, such as not allowing any metal near the machine and cause damage to the machine or worse the patient.

perhaps for the last sentence you should explain more why you fell in love with the machines and the people there rather than the safety measures of the machine
