You mean Roentgen? Sorry mixed physical units names ``Rankine'' is a rarely used scale for temperature. Proper physics units would be something like 10 micro rads. 1 rad is 0.01J/kg of radition energy. Roentgen (93 ergs/g) are used for radition measurement absorbotion by soft body tissue, not the right unit when dealing with semiconductors :-). Now should we talk about rep's and rem's, or perhaps even RBE's? -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Reliable computers for FreeBSD
