Radioactivity problem, please help?

I did some study on this concept on my own, and even reached a tutor, but I still do not understand at all (and neither did my tutor unfortunately). Please help me if you know how, and be very detailed. Only the usual response help me at all, I have to know how to do it myself I can do on my end. Thanks! 1. If you have 2.78 mCi nickel-60 (T1 / 2 = 373 seconds) now, which is one minute activity from now on bequerels units? 2. Want to give 4.26 mCi of cobalt-58 (T1 / 2 = 71.3 days) to a hospital in Mozambique. Due to shipping regulations, this material must go by boat. We guarantee the delivery of material in 22 days. How much cobalt-58 that is placed in the container, so that the hospital receives the correct amount of radiation?

Not me, but perhaps the chemistry of these sites may be: http://chemistry.about.com/od/homeworkhelp/Chemistry_Homework_Help.htm http://www.webelements.com/
