Liquid-liquid Extraction of 99mTc

Learning Goals

After having completed this exercise you should know the following:

• Have practical experience on working with open radioactive sources.
  *Know basic safety rules and procedures for working with modest amounts of radioactivity.
  *Know how to use a radiation monitor.
  *Get practical experience with measuring ("counting") radioactive samples, and understand the inherent uncertainty using proportional counters and NaI (<span class="texhtml">γ</span>-spectroscopy detectors.
  *Understand the relationship between disintegration rate and count rate.
