| Metrology area, Sub-field | Ionizing Radiation, Section I (x and gamma rays, electrons) |
| Description | Measurement of air kerma for Cobalt 60 |
| Time of measurements | 2002 |
| Status | Approved for equivalence |
| Final Reports of the comparisons | |
| Measurand | Air kerma |
| Parameters | Radiation type: Co-60 gamma rays |
| Transfer device | Three cavity ionization chambers |
| Comparison type | Key Comparison |
| Consultative Committee | CCRI (Consultative Committee for Ionizing Radiation) |
| Conducted by | SIM (Inter-American Metrology System) |
| Comments | This comparison was carried out as a series of bilateral comparisons between NRC and the participating countries. The comparison was archived on 21 September 2016 as it is superseeded by more recent comparisons for all participants. Degrees of equivalence obtained in SIM.RI(I)-K1 in 2002 are now superseeded by more recent results, which are available from the BIPM.RI(I)-K1 Results page. |
