a) The Department provides the following calibration services under accreditation by the Conference of Radiation Control Program Directors, Inc.

1. 1) X-ray Calibrations. 5 beam codes at 32 mR/sec. This service is available for the Radcal MDH 1015 x-ray monitor only. The available beam codes are:

   BEAM CODE	HALF-VALUE LAYER	HOMOGENEITY COEFFICIENT
   L	80	1.81 mm Aluminum	0.59
   L	100	2.82 mm Aluminum	0.59
   M	30	0.36 mm Aluminum	0.65
   M	50	1.03 mm Aluminum	0.64
   M	100	4.96 mm Aluminum	0.73

2. 2) Gamma Ray Calibrations. 1 beam code. This service is available only for ion chamber and energy compensated G-M tube instruments.

   BEAM CODE	INTENSITIES
   Cs-137	.005 - 40 R/hr

b) The Department also provides the following services, which are not performed under accreditation.

1. 1) Microrem Meter Calibrations. 2 points per scale, gamma intensity range available to 0.015 mR/hr.
2. 2) Pocket Dosimeter Calibrations. 1 point gamma radiation up to 200 R.
3. 3) Count-Rate Instrument Calibrations. Pulse rate at 2 points per scale. Alpha probe response is checked at 2 points. Beta-gamma probes are checked at 1 point. Other checks may be performed, depending on each instrument and probe combination.
