SPIR-QUANTA

Liquid or Solid Sample Contamination

Measurement

SPIR-Quanta is a system based on the SPIR-Ident

product line technology, which provides reliable and

sensitive identication, and quantication of gamma

radionuclides.

Low detection limits are achieved through Marinelli

geometry, large 3’’x3’’ NaI scintillator and lead shielding.

Measurement protocols are predened or user

customized. Predened protocols include nuclear

accident contamination with Cs137, Cs134, I131

concentration measurement.

Customized protocols are possible over a wide library

covering applications for nuclear installations, dismant-

ling/decommisioning and medical radionuclides release

check.

The PC software allows easy and step by step measu-

rement process. The measurement sheet lists identied

radionuclides, related quantication in activity unit.

Transportable size and weight make it convenient to

use on the eld. Only a laptop with an Ethernet port is

needed.

FEATURES

Very high sensitivity due to large detector size, Marinelli

beaker geometry and algorithm capability

● Lead enclosure for 1 and 2 liters Marinelli beakers

● Very robust processing against false positive

● Simple procedure

● Preset and user denable protocols

● Auto energy calibration

SPIR-Quanta Detection and Identification - Risks Prevention DESCRIPTION EXAMPLE OF PERFORMANCES SPIR-Quanta uses a 3”x3” NaI(Tl) detector, coupled to a spectrometric base to generate spectra from the samples contained in a Marinelli beaker placed inside of a 30mm thick lead shielded enclosure. Performances has been widely evaluated using actual and MCNP generated spectra for various intended isotopes and various material.
