2. A vial contains 1900 MBq of Technetium-99m on the 18th June 2014 at 06:00. How much will it contain at 07:00 on the 19th June 2014? Please input your answer in Bq and Ci. Note :- When a vial contains 1900 MBq of Technetium- 99m. Kindly give the correct answer.
Iridium-192, a beta emitter, is used in medicine to treat certain cancers. The 192Ir is used as a wire and inserted near the tumor for a given amount of time and then removed. The 192Ir wire is coated with pure platinum, and is sold by diameter and amount of radiation emitted. One type of wire sold is 221 mm long, has a linear apparent activity of 30–130 MBq/cm, an active diameter (which is the iridium-192) of 0.1 mm, and an outer diameter (the platinum) of 0.3 mm.
(a) How much 192Ir is in the wire if the apparent activity is 99 MBq/cm?Enter your answer in scientific notation:
(b) If the wire is placed in the tumor for 60 hours, how much radiation is absorbed by the tumor?
