Hello Sharon, Thanks for answer me. Answering your question, now i´m studing to be Master in Ocupational Health. I wanna study radioprotection. Now, i only study, but in 2006 i´m going to learn nursing at the graduation and tecnical curses. In ocupational health i have the pos-graduation but i never worked in the area; i wanna do it next year. Sorry, I don´t write in english a long long time...my gramatical is so bad. So, tell me, what do you do in ocupational health? Hugs Katia
