When working with radioactive materials you must use radiation detection instruments. Which of the following instruments require
vampirchik [111]

Geiger-Muller tube is instruments requires you test three times the background of the work area.

<u>Explanation</u>:

These detectors are gas filled detectors and hence requires time for responding to the value. This time is taken because during this period it collects the electric charges and features of the electric circuit. It also gets stabilized during this period. This device has thumb rule i.e one must wait or hold for at the least 3 times the time constant before getting the precise and accurate reading. The time constant order is 10 seconds for the ionization chamber but for the Geiger counter it can vary from seconds to greater than 20 seconds

Explanation:

Lucille's cells need oxygen. In order for cells to properly function, they need to be oxidized. If Lucille's respiratory system is not working then her body cannot receive the oxygen that it needs in order to send to her blood cells. The circulatory system pumps Lucilles's blood around her body but if there is no oxygen, Lucille's cells/heart cannot properly function, this making it difficult for her to play soccer.
