Andy,
As a successful user of DownHoleSat for a number of years let me welcome to this discussion group. In Shell, as with other Oil Producing Companies, throughout the world we handle vast amounts of connate waters co-produced with the oil. Chemically these waters are diverse in composition and generally unstable. In many cases mineral scales are produced which can cause millions of dollars in lost revenue. Generally the scales are calcium carbonate (calcite, aragonite), calcium sulphate (gypsum), strontium sulphate (celestite), barium sulphate (barite) and iron sulphide (pyrites). In some cases, which may be of relevance to your research, radio active scales are produced. These may be radium sulphate, lead-210 sulphide, actinium sulphate and in one case I detected pure Lead-210. In the UK the National Radiological Protection Board is the statutory body responsible for all things radio-active including biological markers and forensic science. NRPB have an excellent WWW site on http://nrpb.org.uk. Use Altavista and search on "nrpb" Try http://www.nrpb.org.uk/Aag.htm for leaflets. Although I have not trying searching try Altavista and search "Home Office" as they are the body in the UK responsible for police forensic science.
Good Luck
Geoff Fowler
