Safeguards account for the controlled use of nuclear material.

Nuclear facilities must keep track of all materials.

ALDERMASTON.a SEVERE DE---CONTAMINATION programme began to eliminate RADIATION and TOXIC HAZARD.This state of affairs came to light due to a Mrs Isobelle HARDWICH a Scientrist who had had a low blood count came to work in part of our Laboratory and as a safety precaution she requested a that it be monitored by the RADIATION SECTION.Apparently this work shouild have been carried out under Hazard conditions but due to lack of information this was not done by the Metallurgists and the work just went ahead.All staff involved were sent for Urine and Blood Count Tests and opronounced fit.I had a low blood count and had further tests by Dr WILKINSON a Manchester Specialist.The medical staff assured me that eveything was alright even though I had actually handled more URANIUM and for much longer periods {weekends etc}than any other Technician in the Section.All this happened before the strict Medical Supervision which Dr WALLACE mentioned in his letter which you have.After DE---CONTAMINATION was completed Dr EVANS went to AMERICA and I was transferred to another Metallurgist Mr E. LLOYD who had in use various projects in progress which were mostly conventional metallurgy,{i.e.Tensile tests,corrosion experiments etc}and most of my initial work was making specimens and assisting in these tests.Then a new project started on Special Welding of materials like ZIRCONIUM,NROBIUM and MOLYBDENUM in controlled atmospheres.My first job was designing and making a Vacuum Bell Jar Unit for this purpose.The Unit comprised of a 24 inch diameter x24 inch deep x 3/8 inch thick glass jar which was used as a cover over a table with a fixed Welding Electrode and traversing mechanisms.The interior was pumped out with a Rotary and Diffussion Vacuum pumps and then filled with high purity ARGON {99.995} to about 1/3 rd of an atmosphere.The specimen then to be welded was then traversed radially or laterally in a jig as
