ANUSUCHAK is a novel gamma radiation detection device based on an approach to provide desired performance, low cost, mass production and small dimensions. ANUSUCHAK is capable of detection of elevated levels of gamma radiation in real time. This device can be connected to a smart phone or PC/Laptop for real time numerical and graphical display. Also, the data is saved in files with time stamp and GPS coordinates for visualization at any time and for generating reports.

1. Monitoring of trafficking of radioactive materials outside regulatory areas for preventions of threats: airports, railway stations, border posts, police, work places, etc.
2. Military: Radioactivity assessment in battle fields.
3. Emergency response management for assessment of activity and demarcation of zones based on the activity.

A compact, low-cost, widely deployable gamma-ray detection device is essential for prevention of radiological incident or emergency response management in the case of an incident. Such a device has particularly applications in the field of national security and military such as emergency response, battlefield assessment, monitoring at borders, airports, railway stations and personal exposure monitoring. A gamma detection device along with smart phone of PC/laptop interface has been developed by BARC. This device uses a PIN silicon detector for generation of electronics signal corresponding to each gamma ray interaction with the detector material. A low power signal processing electronics amplifies and processes the signal for counting by a microcontroller. The device is powered through USB 2.0 interface and the data is displayed with time stamp and GPS coordinates using a Android or Windows based software. The device can be further revised for wireless/blue tooth connectivity or battery based standalone system.

1. Based on a silicon PIN detector for achieving small size and low power/low voltage operation, very simple to use without special training.
2. USB 2.0 interface to smart phone or PC/Laptop for power and display of data/record of data.
3. Provision to set various parameters with password control.
4. Graphical and numerical display of data.
5. Audio and visual alarms when the radiation exceeds warning or danger level.
6. Recorded data is linked to GPS coordinates of the location with indication on Google Map.
