RadTarge-Mini is a compact, robust and high performance radiation detection system. It interfaces via
Bluetooth to mobile devices such as phones and tablets running the RadMay mobile App. Together
RadTarge-Mini and RadMay offer a high performance, versatile and low cost radiation detection and
dosimetry solution which addresses a very wide range of applications and use cases.
RadTarge-Mini detects ionizing radiation by means of a scintillator and a high performance photo
detector. The readout of the photo detector signals is realized through our patented MVT or Multi
Voltage Threshold technique. This puts RadTarge-Mini performance in a class of its own. Its detection
sensitivity is up to 20 times higher than that of traditional Geiger-Müller or film based systems. A low
energy threshold of 20 keV helps reliably detect radiation sources commonly encountered in industry
and medical imaging. A maximum count rate of 2 million counts/second serves to cover worst case
scenarios in high radiation environments.
The RadMay mobile App and cloud service is a flexible and intuitive tool to view, save and manage
dose and dosimetric data received from RadTarge-Mini. The user can configure alarm thresholds,
accumulate dosimetric data, map and visualize the radiation environment using GPS geo-location. All
data is safely stored to the RAYCloud which offers a wide range of review and analysis functions.

3.1 Detector and Radiation
RadTarge-Mini uses a YSO scintillation crystal coupled with SiPM as the detector to
measure gamma and X-rays. It can measure dose equivalent rate and cumulative dose.
3.2 Dose Display
The device can display real-time dose equivalent rate and cumulative dose. Users can
switch the units between international standard units and traditional units through the RadMay app.

3.4 Alarm Modes
According to the American National Standard for Dosimetry, ANSI HPS N13.11 Personnel
Dosimetry Performance - Criteria for Testing, the device should have at least one alarm mode on.
RadTarge-Mini supports three alarm modes: audible, vibrating, and audible & vibrating. Users can
set the alarm mode via RadMay. The alarm response time is less than 8 seconds when the
radiation level passes 10 μSv/h from the background radiation level. Users can set the alarm
threshold within the measurement ranges:
· 1μSv/h Real-time dose rate pre-alarm threshold, suggested value: 1 μSv/h
· 10μSv/h Real-time dose rate alarm threshold, suggested value: 10 μSv/h
· 1mSv Cumulative pre-alarm threshold, suggested value: 1 mSv
· 10mSv Cumulative alarm threshold, suggested value: 10 mSv
· Pre-alarm frequency is 1 time/second, alarm frequency is 2 times/second.
3.5 Data Transfer and Storage
Data Transfer: Built-in Bluetooth 4.0 module transfers data to RadMay to manage dosage data.
Data Storage: Built-in flash storage can store cumulative dose for 1 year and real-time dose alarm
events for 1 month.
RadMay is a mobile app designed to manage dosage data from RadTarge-Mini. Additionally, using
data from the smartphone's GPS, RadMay can establish the global radiation distribution and
personal lifetime dosage log by recording, summarizing and analyzing radiation data.

Real-Time Dosage (Dose Equivalent Rate)：
Represents the health effects of ionizing radiation on the human body per unit of time. In the SI
system of units, the unit of measure is μSv/h or mSv/h. 1 Sv/h = 1000 mSv/h，1 mSv/h = 10 00 μ
Sv/h
Cumulative Dose：
1000μSv；Represents the health effects of ionizing radiation on the human body over a period of
time. In the Si system of units, the unit of measure is μSv or mSv.
Lifetime Cumulative Dose：
Lifetime cumulative dose is the cumulative dose since the user registered his or her account.
Periodic Cumulative Dose:
The cumulative dose from the time point defined by the user to now. Users can compare this value
to standard annual cumulative dose.
Custom Periodic Dose:
The cumulative dose between the start and stop time points defined by the user.
