Question:
A shielded y-ray source yields a dose rate of 0.052rad/h at a distance of 1.0m for an average-sized person. If workers are allowed a maximum dose of 5.0rem in 1 year, how close to the source may they operate, assuming a 40-h work week? Assume that the intensity of radiation falls of as the square of the distance. (It actually falls of more rapidly than 1/r2 because of absorption in the air, so your answer will give a better-than-permissible value).

I have recently received the degree of PhD. In Physics by the Universidade Federal do Maranhão after spending a term in Durham University, as I have been awarded a scholarship from a Brazilian mobility program. During my PhD. I have performed research mainly in Theoretical Physics and published works in distinguished Journals (check my ORCID: https://orcid.org/0000-0002-4324-1184).
During my BSc. I have been awarded a scholarship to study for a year in the University of Evansville, where I have worked in detection-analysis of photon correlations in the the Photonics Laboratory. There I was a tutor in Electromagnetism, Classical Mechanics and Calculus for most of that year (2012).
I am very dedicated, honest and a fast learner, but most of all, I value a job well done.
