Understanding the Geiger-Müller Tube

What are the main components that the GM tube can be connected to?

• Oscilloscope, spectrum analyzer, and signal generator

• Scale meter, rate meter, and speaker

• Thermometer, barometer, and hygrometer

• Voltmeter, ammeter, and ohmmeter

Why is a thin mica window used in the GM tube?

• To prevent gas from escaping

• To allow light to enter the tube

• To enable alpha, beta, and gamma particles to enter

• To reflect sound waves

What is the purpose of the positive and negative electrodes in the GM tube?

• To generate heat

• To create a magnetic field

• To facilitate ionization and current flow

• To produce light

What happens when a radioactive source enters the GM tube?

• The gas inside the tube is ionized

• The tube emits light

• The tube vibrates

• The tube changes color

How does the GM tube produce an electric pulse?

• By heating the gas

• By cooling the gas

• By ionizing the gas and creating charged particles

• By compressing the gas

What role does the speaker play when connected to the GM tube?

• It cools the GM tube

• It produces a sound for each emission detected

• It amplifies the electric pulse

• It measures the temperature

How can the GM tube help in comparing radioactive emissions from different sources?

• By analyzing the color of the sources

• By counting the number of emissions per minute

• By weighing the sources

• By measuring the temperature of the sources

What is considered a normal emission rate for most rocks?

• 1 or 2 emissions per minute

• 100 emissions per minute

• 500 emissions per minute

• 1000 emissions per minute

What should you do if a rock emits 200 emissions per minute?

• Ignore it, as it's normal

• Consider it highly radioactive

• Use it as a paperweight

• Paint it to reduce emissions

Why might an amplifier be connected to the GM tube?

• To cool down the GM tube

• To change the color of the emissions

• To decrease the current for safety

• To increase the current for better detection
