How could you reduce the relative uncertainty in the background count rate in the Geiger counter?
How could you reduce the relative uncertainty in the background count rate in the Geiger counter?
*Uncertainty in background counts The background counts (C) detected in 5 minutes by a Geiger counter is found to be C = 321. The background count rate per minute (C/min) can be easily determined. What is the uncertainty in this value (ΔC/min)? Express your answer to one decimal place.
A Geiger counter registers a count rate of 7,600 counts per minute from a sample of a radioisotope. Ten minutes later, the count rate is 1,900 counts per minute. What is the half-life of the radioisotope?
This question is regarding background radiation using a Geiger-Muller tube and (lead) absorbers. The question is how does background radiation compare with and without absorbers, and what this difference tells you about the energy of background particles. Question 1.2 How does the background radiation compare when there is an absorber in place? What does this tell you about the energy of the background particles? Background radiation is usually high energy cosmic rays from sources outside the earth. They make it...
Part A You are using a Geiger counter to measure the activity of a radioactive substance over the course of several minutes. If the reading of 400. counts has diminished to 100. counts after 89.3 minutes , what is the half-life of this substance? Express your answer with the appropriate units.

A) You are using a Geiger counter to measure the activity of a radioactive substance over the course of several minutes. If the reading of 400. counts has diminished to 100. counts after 48.2 minutes , what is the half-life of this substance? B) An unknown radioactive substance has a half-life of 3.20 hours . If 24.3 g of the substance is currently present, what mass A0 was present 8.00 hours ago? C) Americium-241 is used in some smoke detectors....

Can you answer question correctly The radiation detector known as a Geiger counter consists of a rb = 39 mm radius cylindrical metal tube sealed at the ends with a ra-1.7 mm radius wire along the axis as shown below. The wire and the cylinder are separated by a low pressure gas whose dielectric strength is 6.4 x 106v/m. What is the maximum potential difference between the wire and the tube? Give your answer in Volts with scientific notation to...
A Geier counter registers a count rate of 6,000 counts per minute from a sample of a radioisotope. Eighteen minutes later, the count rate is 1,500 counts per minute. What is the half-life of the radioisotope? ________ minutes
