Description
Portable radiation scanners (PRS) are instruments with the
highest sensitivity, which an individual can still utilize in a
mobile mode. The main area of PRSs applications is mobile
radiation screening for pedestrians, vehicles and cargo in
public/urban areas, or at border crossing points where the
deployment of standard fixed-installed RPM is not feasible
or practical. The RPS can be used as a primary tool for
detection of orphan sources or radiological area
reconnaissance.
NSS1-rev.1
par 6.6.1
Being similar in its intended application to an RID, the
instrument has the same main functions: detection, location,
dose rate indication and radionuclide identification. The
instrument design however significantly differs from that of
RID, originating from its larger size and intended use for
cover detection.
Configuration
The principal components of the instruments are gamma and
neutron radiation detectors, a multichannel analyzer (if an
PRS features radionuclide identification), a processing unit,
a satellite navigation system, a graphic indicator, alarm
annunciator (audio signal, voice output on Personal Digital
Assistor (PDA) speaker or headset, vibration alarm) and
rechargeable batteries. The instrument housing interior
should not attract public attention during a covert survey.

Explanation
/limitations
ITRAP+10 specific
requirements
If the instrument is supposed to be shipped by air, it
shall be safe to do so without the need of declaring the
instrument as dangerous goods due to the possible
presence of calibration sources and or pressurized gas
counters

single-phase a.c. supply voltage of 230 V with a
supply voltage tolerance of + 10 % – 15 % and a
supply frequency of 47 Hz to 51 Hz.
GUI requirements
The following information and control shall be
provided at the user display:
(a) Strip-chart display of gamma and neutron
counts
(b) Spectral display from gamma detectors, if
applicable
(c) List of radionuclide identified (if applicable)
(d) Real-time access to data stored
(e) Real-time mapping with GPS data and alarm

gamma
The instrument shall alarm when it is exposed to an
increase in the ambient radiation level greater than
0.05 μSv/h within 1 s of the step change. The PRS
should meet this requirement in a gamma energy
range from 0.05 MeV to 1.33 MeV.
