Neutron-activation analysis is much more widely used than charged-particle activation. Why do you suppose that is true?
Introduction:
Activation analysis is a method of elemental analysis in which nuclei are made radioactive by irradiation in a suitable source of activating particles and subsequent. Any means of inducing radioactivity (neutron, photon or charged particle irradiation) can be used for activation analysis.

- Discuss an active assay of nuclear materials using a neutron source and prompt neutron measurements. How to discriminate prompt fission neutrons from the neutrons emitted by the source?There are an alpha, beta and gamma particles that you all need to use only once. One of them can be thrown away, one of them needs to be hidden in your pocket, and you need to hold the last one. In order to stay safe from radioactivity, where should you place them? Throw away: ____ In your pocket:____ In your hand:_____ Options: Beta, Alpha, Gamma. Please explain fully. Thank you!Cs-137 produces beta-minus particles. What types of interaction are likely to occur if a Cs-137 source is shielded in glass? In lead?
- Suppose that you want to find out how much gasoline is in an underground storage tank. You pour in 1 gallon of gasoline that contains some radioactive material with a long half-life that gives off 5000 counts per minute. The next day, you remove a gallon from the underground tank and measure its radioactivity to be 10 counts per minute. How much gasoline is in the tank?Why is a chain reaction more likely in a big piece of uranium than it is in a small piece?The isotopes 103 Pd and 137 Cs have different radial dose functions when used in brachytherapy (Figure16.13). Why might you use one versus the other in interstitial radiation therapy?
