Practical For Measuring Count Rate With Distance

Question 1

How ti ensure count rate measured is ACCURATE

Answer 1

Measure for LONG PERIODS
- this ensures that is at the end of the day it’s all probability, it reduces the error of probability when measuring count rate . As now it’s more likely to be its true value!

Question 2

What graph does gamma count vs time look like and same for alpha beta?

Answer 2

Gamma = inverse square due ti I (which is count rate) prop to 1/r2

Alpha beta penetration power too weak such thst their activity is less than what the inverse square law for them suggests
