This is a professional device for official measurements, which measures the level of gamma background, beta contamination, accumulated dose and its accumulation time. Prompt evaluation of gamma background is performed within 10 seconds. With the help of GS Ecotest application measurement results are transferred to smartphones and tablets running Android™ OS via Bluetooth channel in real time.
The GS Ecotest application is available on Google Play:
Measurement results can also be transferred to a personal computer.
TERRA has a large display with luminescent backlight, which simultaneously indicates units of measurement, measurement error, threshold level and real time, as well as ten-segment analog indicator of registered radiation intensity. The dosimeter has a built-in memory for 1200 measurements. Sound, vibration and sound-vibration alarms are provided for convenience of use.
The device is in operational service with the Ukrainian Army, it is included in the equipment list of the State Emergency Service of Ukraine, and used for the purposes of the Security Service of Ukraine, Ministry of Internal Affairs of Ukraine, and the State Border Guard Service of Ukraine.

Potential sources ofradiation
Food (especially berries and mushrooms)
Food (especially berries and mushrooms) will definitely accumulate radiation if grow in contaminated areas. These are not the best ingredients for your nutrition or home-made jam. Mushrooms tend to absorb radiation from soil as well. It is important to know that radiation which gets inside of our bodies is the most dangerous. Check radiation safety of your food (especially mushrooms and berries) and enjoy safe cooking.
Home and office
It is great to have excellent workplace in a comfortable office or have some rest sitting in your favorite chair at home. But is there any chance you can be exposed to radiation? Unfortunately, yes. Furniture can be made of radioactive wood as it absorbs radiation. Granite can have high radiation level as well. Check the radiation level of all your furniture.
Construction
Remember that construction materials can contain natural radionuclides. That is why when building, choose the materials carefully as they can pose a great threat to your health. When moving to a new place, be sure to check that no radiation is there.
Playground
Radiologically contaminated toys can harm your child’s health. Even a sandbox on a playground can pose a danger. Control radiation level around to be sure you chose a right place to play with your kids.
Cash
Cash can be radiologically contaminated for definite purposes. The most common one is to track money during special operations, but sometimes these banknotes can end up in our wallets. Even a small amount of radiologically contaminated banknotes can harm a large number of people. Be safe when deal with cash.
Garden
Radioactive fallouts may contaminate soils in any corner of the world. Be sure to check radiation level in your garden if you don’t want to raise contaminated fruits and vegetables. Radiation which gets inside of our bodies is the most dangerous.
Travelling
When travelling you can come across the places of buried radioactive scrap metals or others contaminated objects. Caving is such a fun if you are not exposed to high radiation level there. It is better to enjoy outside activities if they’re safe.
Jewelry
We should pay great attention when buying necklaces, rings or other jewelry. Precious metals and stones can have high radiation level, especially zirconium which is the most commonly used in jewelry items. That is why you should be careful if you don’t want to pay “high” price. Jewelry should be decorative, not destructive.
