1 The radioactive iodine is usually given in pill form, although it can be given in liquid form. 2  Some people have trouble swallowing pills. 3  If you do, tell your doctor in Nuclear Medicine before your treatment.
Shelf Life. While an alkaline battery is reliable, it has a shelf life of about 7 to 10 years. Around that time, the chemicals within the battery become stagnant and no longer produce a chemical reaction to power the battery. Some people believe that placing unused batteries in a freezer extends their shelf life.
Not really, but it depends too on `how long after the expiration date` you're talking about. If it's only a few months, it should still be close. But if it's a year or so, then even less. Batteries such as dry cells operate on a chemical reaction. This reaction continues even as the battery is sitting on the shelf, and if left long enough, it'll essentially burn itself out. One of the tricks I use for storing batteries is putting them into the freezer.
