Why I Want to Become a Radiographer
I was laid off from my job November, 3 2003. This news was shocking and scary at first, but my employer later informed me of a government program that offered to send unemployed workers to school, and that made the news a bit easier to take. I was defiantly going to take government up on their offer, so I had to decide what I wanted my major to be. After thinking it over for a while, I decided to major in radiography. There are several reasons why I want to be a radiographer, including a more challenging career, better pay, and job security.
The first reason I want to be a radiographer is that I would like to have a more challenging career. My previous job was not challenging at all. It was manufacturing work, and I was required to learn what to do and then do it over and over all day. From what I have learned about radiography, I would be working in a high tech professional environment, which would require me to continue my education in order to keep up with new technology. A radiographer is responsible for the patents under his or her care and to use what he or she has learned to give the best care possible. As professionals, radiographers are given more respect and trust, enabling them to work with less supervision and to make decisions on their own.
Positions that require one to be responsible and trustworthy usually have a higher rate of pay, which is another reason why I would like to become a radiographer. Most people want more money and I am certainly one of those people. I worked hard at my last job to move up and I did move up somewhat, but because the company that I worked for was steadily going under and in danger of closing I never did get where I wanted to be. I have learned through research I have done that after training, which takes about two years, I can make much more as a radiographer than I ever could have as a factory worker.
The future of manufacturing in the United States has become unstable, which has lead to countless factory closings, especially in the textile industry. Most everyone needs a job, but in my situation I am glad I was laid off. Being laid off from my job has given me the opportunity to go back to school and train for a more secure future in the healthcare industry. A career in healthcare as a radiographer is secure, because as long as there are people in this country in need of medical treatment I will have a job. Unlike manufactures that look to far away countries such as China or Korea to satisfy their needs, people in need of medical attention will seek the closest facility available, which is in their own communities.
As I have mentioned, becoming a radiographer will be a great career change for me, because I want to do more satisfying work and use what I have learned to help people. I want a career that will provide more income and according to my research radiographers are compensated very well. And also I do not want to have to worry if I will have a job tomorrow. There will most likely always be a need for healthcare workers, and I think it is a great field of work to get into.
