What is the half-life of Candium? (i.e., What number of shakes are necessary to reduce the radioactive members to one-half?)

a. 713 million (7.13 seconds of shakes)
b. 6 million (6 seconds of shakes)
c. 813 million years (8.13 seconds or shakes)

1 answer

The question refers to "Candium," which is not a known element or material. Without information about the specific properties and characteristics of Candium, it is not possible to determine its half-life or the number of shakes necessary to reduce its radioactive members to one-half. The given options do not provide a clear answer as they mention different time scales and shake durations.
