Question

When the radiation level coming from a radioiodine therapy patient in isolation is measured, how should it be measured?

1) Using a Geiger-Muller counter
2) Using a spectrometer
3) Using a thermometer
4) Using a pH meter

Answer 1

The radiation level from a radioiodine therapy patient should be measured using a Geiger-Müller counter, as it is the most well-known device for radiation detection and measurement.

Step-by-step explanation:

When measuring the radiation level coming from a radioiodine therapy patient in isolation, the appropriate instrument to use is a Geiger-Müller counter, commonly known as a Geiger counter. This device detects and measures radiation by causing the ionization of gas within a Geiger-Müller tube, with the rate of ionization being proportional to the amount of radiation present. Other devices, such as scintillation counters and radiation dosimeters, can also detect radiation but the Geiger counter is the best-known instrument for radiation exposure measurement.
