you mean you want to add tracer to the soil samples. Which radionuclide are you considering?
Do you have any specific radionuclide in mind. And why alcholic soultion. We have been spiking it with acidic solution. Is it for analytical purpose or a field experiment. Do let me know may be we can guide you in this.
1) Alcoholic solution because it can be homogeneously mixed with bulk soil and easily evaporated without disturbing significantly the soil system.
2) Cs-137.
3) A lab (batch) experiment.
Thanks, Dr. Saifuddin Iqbaluddin.
is this related to Cs-137 determination in soil or some other experiment
if you need to add tracer to soil, I will still suggest you use an acidic solution and it can easily evaporate if you keep in oven at 95 oC. Am not sure in this case you would like to have 137Cs tracer or 134Cs tracer. Usually for 137Cs determination we use 134Cs tracer. Are you planning to do a gamma spectrometry then for 137Cs determination?
Dear Dr. I'm afraid that both of your suggestions are unsuited to the soil samples I'm working with (tropical, amphoteric, acidic, highly weathered). Firstly, either an acidic solution as temperatures above 40°C would introduce an important disturbance of the ions exchange system. Secondly, I'm studying partition mechanisms of Cs-137 within tropical soils, not the ways of Cs-137 determination in soil matrices. I'm using a NaI detector for gamma spectrometry.
Intresting so you are getting 137Cs in soil profile, due to vertical precipitation migration. use acetone in this case.
