SOEKS Defender is the "big brother" of SOEKS 01M. This device went on sale in April 2012. The retail price for this device is higher than that for SOEKS 01M by RUB 500. The price includes rechargeable batteries (unlike SOEKS 01M, which is supplied with regular batteries), an adapter, a charging USB cable, and a robust rubber-coated housing. In addition, the device can also measure cumulative doses over a long period of time (more than 1 year).

Human exposure to radiation is called irradiation. In this process, radiation energy is transmitted to cells and destroys them. Irradiation may cause various diseases including infectious complications, metabolic disorders, malignant tumors, infertility, and cataracts. The impact of radiation is especially harmful to dividing cells; this is why radiation is so dangerous for children.
When people fly in airplanes at an altitude of ten kilometers, they lose the shielding protection of the Earth's atmosphere, which substantially increases additional exposure to space radiation at high altitudes because of a thin atmospheric layer absorbing cosmic rays. Gamma radiation, which is the most dangerous, is not stopped by the body of an airplane. Air travelers do not complain because radiation has no color, odor or taste; its consequences may appear only years later.
For example, a transatlantic flight from the USA to Europe involves prolonged exposure of a human body to cosmic radiation at approximately 0.05 µSv. At an altitude of about 10.5 km, the shielding effect of the Earth's atmosphere is partially lost; as a result, the crew and passengers on board receive small additional doses of radiation.
Jet pilots and other crew members who frequently fly across the Atlantic or the continent may regularly accumulate radiation doses exceeding 5 µSv per year, i.e. the maximum permissible exposure for ordinary people (the average limit for Western Europe).
Officially, flight crew members should be classed as radiation workers but in reality this never happens. Doses received by them are on average higher than those received by the overwhelming majority of workers from other professions, including hospital staff and workers in nuclear power plants.
Radiation which aircrew members are exposed to is not man-made; indeed, it is inherently natural and always exists at high altitudes. The risks, however, are man-made: when people spend all their working hours at an altitude of 10.5 km from the ground, they run a higher risk compared to natural conditions.
