I seem to work all days of the week but it has paid off. I have a preliminary version of the chemistry we can apply to our samples. Finally I have adapted my automatic machine to handle this change in chemistry. We are to analyse radioactive isotopes of caesium, strontium, technetium, iodine, plutonium and neptunium in the same sample: Perhaps also isotopes of radium. I will train two of our technicians this week and then work with them the coming month to perform the separations.
