During the last year of high school just before we sat for the University Entrance Exam, we had to complete a theory component on radiation as a part of the Physics curriculum. That chapter contained a reaction where a uranium atom is combined with a neutron. At the end of the reaction, three more neutrons will be released. I was confused by this fact and asked my teacher how it happens - one neutron in and three out!! My teacher didn't know the answer. She said 'Why don't you find the answer yourself one day?'. I remember thinking that someday I might!
Two years after that, at the beginning of my second year in university as an undergraduate, I saw 'Introduction to Nuclear Science" among the other modules in the curriculum. And I told my friend "This is new. It's the first time I heard of this subject. I want to learn this. It sounds interesting". So, driven by my curiosity, though unknowingly, I started on my path to becoming a radiation biologist, where I learned about fission reactions in which a neutron is bombarded to a uranium atom and the result would be two new isotopes and three neutrons!!
