Technical Data

(a) SCINTILLATION DETECTORS

Nucleonix Systems offers wide range of NaI Scintillation Detectors of different sizes both with flat & well type crystals, to meet the requirements of wide range of users for Gamma ray spectrometry measurements.
Scintillation detectors offered include 1"x1" & 2"x2" NaI integral assemblies with built-in pre-amplifiers. These detector assemblies give excellent stability, superior performance & good resolution in the range of 8.0 to 9.5% for Cs-137. Scintillation detectors of other sizes can be offered against user specific requirements also. For teaching labs we recommned 1"x1" or 2"x2" NaI detector with this integral model.

(b) GAMMA REFERENCE STANDARD SET TYPE GS 290

Gamma Reference Standard Set Type: GS290 consists of a set of FIVE Gamma sources evaporated & sealed on 25mm dia x 5mm plastic disc covering SIX photopeak energies in the range of 3 to 5 micro curie. A reference chart for this is given below. The accuracy of these sources is in the range of +/-10%. All these dics sources are enclosed in a box made of acrylic sheet and supplied.
