|Exposure and exposure rate accuracy|
Basic accuracy of 35050AT: ± 1% of reading ± 2 range resolution steps over range of 18° C to 28° C and ± 2% of reading ± 2 range resolution steps over the full operating temperature range of 0° C to 50° C.
Note: A 3% NIST-traceable calibration is provided with each system and includes effects of 35050AT, 96035B, and 96020C.
Exposure time measurement
Exposure time accuracy: ± 0.1% of reading: ± 0.2 msec
Maximum exposure time: 6.5 s
Measurement resolution: 0.2 ms
kVp/Dose/Time: Single-shot ("all-in-one" exposure), direct-beam measurement of exposure, kVp, and time; autoranging across three-decade ranges; auto reset between exposures; display updates after each exposure
kVp/Rate: Simultaneous measurement of kVp and exposure rate
Full sensitivity dose: Autoranging across five decades of sensitive ranges; automatic drift and offset compensation; automatic post-exposure display hold
Full sensitivity rate: Measurement range covers a span from low-level image intensifier measurements to unattenuated, direct beams; automatic offset compensation and nonlinear filtering. Autoranging provides five decades of sensitivity ranges. Display updates once per second
Very low dose rate (VLDR)
This mode is only for making very low dose rate measurements. Nonlinear digital filtering and autoranging provide five decades of sensitivity ranges. Display updates once per second. In this mode, automatic current offset and drift compensation are disabled. As a result, the system can display very low dose rates.
Battery life: -30 hours with six AA alkaline batteries; automatic power-down after user-selected period of
|unattended operation (5 min to 255 min); AC adapter supplied with each 35050AT|
Note: When the AC adapter is in use, the auto power-down feature is disabled, providing continuous operation. User selections for ion chamber, units, kV filter pack,temperature, pressure, and frame are stored in nonvolatile memory before automatic turnoff; eliminates manual reselection at power-up
Bias voltage supply: Fixed electronic bias (-300V); bias voltage removed from triaxial input connector at instrument turnoff
Customization: Allows user to modify contents of nonvolatile memory, including ion chamber and kV filter pack conversion factors, temperature and pressure units, radiation units, and power down interval. A field customization software program is included for use with an IBM™-PC or compatible
35080M interface: Male, two lug BNC
Computer interface: RS-232 using RJ-45 connector; 9,600 baud 8-bit, 1 stop, no parity, xon/xoff; enables fully-programmable operation and waveform display from a PC with optional Excel add-in; powered when connected to computer
Ion chamber input: Triax, BNC; collector and guard positive-biased relative to ion chamber body and dosimeter chassis
Power: 2.1 mm dc power jack, power input for an unregulated 9V, 200 mA adapter with a center negative, 2.1 mm plug
Display: Two-line, 20 character alphanumeric PLED (polymer LED), with 0.5cm character height; indicates all ion chamber/kV filter pack identification information, numerical measurement results, battery level, calibration date and other information
Weight: 6.4 kg (14 lb)
Dimensions (LxWxH): 46 cm x 33 cm x 15 cm (18" x 13" x 6")
Diagnostic Ionization Chambers (96035B and 96020C)
The 96020C and 96035B Diagnostic Ion Chambers are vented-volume, parallel-plate air ionization chambers with side-mounted BNC triaxial connectors. The 96020C Ion Chamber has a nominal volume of 150 cm³, and the 96035B has a nominal volume of 15 cm³. Both ion chambers have a fully-guarded, centrally-located collector plate that provides superior collection efficiency. The patented 96035B has a dual-energy range that enables both diagnostic and mammographic measurements. They are accomplished using the other side as the entrance window.
Energy range: 96035B: 30 kVp to 150 kVP; 20 kVp to 50 kVp for mammographic 96020C: 30 kVp to 150 kVp

35080M Non-Invasive kVp Divider
The 35080M Non-Invasive kVp Divider quickly and accurately measures kV for all modalities. The unit checks both above and below table tubes, and the direct kV values are displayed on either the 35050AT Dosimeter or the 199XRAY Medical ScopeMeter. Derived kV can also be calculated using a storage oscilloscope. The 35080M Non-Invasive kVp Divider is highly portable and eliminates the need for bulky and heavy high-voltage divider tanks--so compact in size that it fits into a shirt pocket.
A patented wide-range filter pack is included with the 35080M Non-Invasive kVp Divider and provides accurate readings for the range of 50 kVp to 150 kVp. Four optional filter packs are available for use with the 35080M Non-Invasive kVp Divider for CT, mammographic, and mobile applications.
