APPLICATION:

 

Whenever the TBM-IC, a fast, sensitive ion chamber

 

instrument is needed, the TBM-IC-MARK-V is the latest in a series. Important for use in medical departments including Oncology, Treatment & Diagnostic Areas, Radiology & Imaging, PET Scanners, and Gamma Knife.

 

DESCRIPTION:

 

The TBM-IC-MARK V is a general purpose Gamma X-Ray Survey Meter known as the “Cutie Pie”. It consists of a 2.5'' dia x 3.5'' long air ion chamber coupled to a stable solid state MOSFET input electrometer with built in A to D converter to read out directly in mR/h or mR. The TBM-IC-MARK V ion chambers are now smaller and lighter. Stable, essentially drift-free electrometer technology.

 

Rate range is 0.1 mR/h to 10.000 mR/h in a single range. Integrated Dose Range is 0.01mR – 100 R in a single range. 180 mg/cm2 graphite lined methacrylate walls accurate ``air equivalence.''

 

Thin (0.5 mg/cm2) Mylar window allows high sensitivity readings for alpha and for low energy Beta such as C14 and X-rays in addition to higher energy Betas, Gammas.

 

This model does not require pressurization facilitating ease of shipment.


 

Unlike other instruments the TBM-IC-Mark-V which


 

protects staff workers by detecting low energy scattered radiation other instruments ignore.
