Chapter 20, Problem 20.51QP
Interpretation Introduction

Interpretation:

 For the given details of 125I , it should be determined how long it will take for the activity of implanted 125I seeds to fall 5.00% of their original value.

Concept Introduction:

  • Unstable nuclei emit radiation spontaneously to become stable nuclei by losing energy. This process of emission of radiation by unstable nuclei is known as radioactive decay.
  • These emitted radiations may be alpha radiations( α ), beta radiations( β ) or gamma radiations( γ )
  • These unstable nuclei are the nuclei with more than 83 protons and which do not lie within the belt of stability.
  • Radioactive decay are in the first order kinetics. Rate of radioactive decay at a time t is,

    Rate of decay at a time 't' = k Nk-Firstorderrateconstant and its unit is t1N-numberofradioactivenucleipresentattime't

    Suppose the number of radioactive nuclei at time zero is N0 and at a time t is Nt ,

    lnNtN0=-kt

  • Half-life of radioactive decay is the time required for a radioactive sample to decay to one half of the atomic nucleus.

    Half-life of the radiation,  t1/2=0.693k

    Half-life and rate constant for radioactive isotopes vary greatly from nucleus to nucleus.

To determine: The time taken for the activity of implanted 125I seeds to fall 5.00% of their original value

Predict the major organic product for this reaction.
3) The following molecule, chloral is a common precursor to chloral hydrate, an acetal type molecule that was a first-generation anesthetic. Draw a mechanism that accounts for tis formation and speculate why it does not require the use of an acid catalyst, like most hemiacetal and acetal reaction: (10 pts) H H₂O
You are a Quality Manager for a very well-known food ingredient company that produces umami powder, and you are responsible for setting specification limits. The net weight (in grams) of bags of unami powder is monitored by taking samples of six bags on an hourly basis during production. The label on every bag reports a contents of 1KG umami powder. The process mean is μ = 1012 g, and when the process is properly adjusted, it varies with σ = 11 g. QUESTION: Your organisation strives to ensure that >99.97% of bags of umami powder produced conforms to specification. What performance process index value is required to achieve this process yield? Calculate PPK using the following formula: Ppk = (USL – mean)/3 σ Ppk = (mean -LSL)/ 3 σ
