Personal Dosimeter DKG-21M

Personal Gamma Radiation Dosimeter

Сonforms to the CE standards
Meets the requirements of IEC 61526 standard
ТУ У 33.2-22362867-010:2007

Description

Direct reading personal dosimeter in a damp and dustproof body with a high

ingress protection rating, designed for use by the Army, Ministry of Emergencies

and Civil Defense in conditions of significant temperature oscillations and high

dustiness of atmosphere.

It can be used either independently or within the automated system of personal

dosimetry control ASIDC-21.

The dosimeter allows storing dose accumulation history with real time reference

in the non-volatile memory, and communicating it to the computer. If the

programmed threshold levels of gamma dose or its rate are exceeded, light and

audio alarms are actuated.

DKG-21M is in operational service with the Ukrainian Army, and is successfully

used by the Army and the units of the Ministry of Emergencies of Kazakhstan.

Purpose of Use

Measurement of gamma and X-ray radiation individual dose equivalent rate (DER).
Measurement of gamma and X-ray radiation individual dose equivalent (DE).
Clock, alarm clock.

Features
IP54 ingress protection rating.

Stand-alone use or use within automated system of personal dosimetry control.

Storage of dose accumulation history in the nonvolatile memory with real time reference.

Transfer of dose accumulation history through the infrared port to the computer.

Blocking the mode of power supply switch off until the data reading procedure finished.

Gamma radiation DER and DE threshold levels programming with the help of the computer or manually with control keys.

Blocking certain indication modes in response to the computer command.

Light and audio alarms when programmed threshold levels exceeded on DER and DE of gamma radiation.

Display automatic switch off if current gamma background is lower than the preset threshold level with instant switching on at:

– pressing any control key;

– gamma background increase above the preset threshold level;

– alarm clock ringing.

Periodic self-testing of batteries and detector.

Energy-compensated Geiger-Muller counter.

Get To Know More About Radiation

Potential Sources Of Radiation

Food (especially berries and mushrooms)

Food (especially berries and mushrooms) will definitely accumulate radiation if grown in contaminated areas. Mushrooms tend to absorb radiation from soil as well. These are not the best ingredients for your nutrition or home-made jam for sure. We know how dangerous radiation is when it gets into our bodies. It’s always wise to check the radiation safety of our food to enjoy a safe and healthy lifestyle.

Home and office

It is always a great thing to have a safe and productive workplace or just be cozy sitting on your favorite couch at home. But even in your most comfortable zones, is there any chance you can be exposed to radiation? Unfortunately, yes. Furniture can be made of radioactive wood as it absorbs radiation. Granites can have high radiation levels 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 levels around to be sure you chose the 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 dealing with cash.

Garden

Radioactive fallouts may contaminate soils in any corner of the world. Be sure to check the radiation levels in your garden if you don’t want to raise contaminated fruits and vegetables. We know that radiation that gets inside of our bodies is the most dangerous.

Travelling

When travelling you can come across the places of buried radioactive scrap metals or other contaminated objects. Caving is such fun if you are not exposed to high radiation levels out there. It is always 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 levels, 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 a "high" price. Jewelry should be decorative, not destructive.
