Assessment of differences and relative differences between the primary facility-specific predicted personal REC estimates in Facility B in 1994 and the arithmetic means of the REC personal measurements collected in 1994 (Stanevich et al., 1997)
| Job | Feasibility study (1994) |
Estimated REC AM (μg m−3) | |||
| n | REC AM (μg m−3) | Difference (μg m−3)a | Relative difference (%)b | ||
| Continuous miner | 26 | 248.4 | 272.7 | −24.3 | −10 |
| Foreman | 6 | 166.3 | 175.9 | −9.6 | −6 |
n, Number of measurements; AM, arithmetic mean of the personal REC measurements.
a
Difference between the AM of the measured REC exposure levels in the 1994 feasibility study and the estimated REC exposure level.
b
Relative difference is the difference divided by the AM of the measured REC exposure levels in the 1994 feasibility study.
