  Thus, when the symbol “->!->” is indicated on the display, the automatic restart of AEDR measurement and beta radiation flux is enabled. It is performed both when the acquired count rate measurement value exceeds the predetermined limits and when the “START” button is pressed. Restart is accompanied by an audible signal.

  If the user opens the shutter before the measurement is finished, the messages “BACKGROUND IS NOT DEFINED”, “measurement of β will be possible not earlier than in (time before the measurement is finished) seconds” and the count rate measurement (γ + β) will start. When the background measurement is finished, ass the display windows are available.

  When beta radiation flux density from other nuclides is measured, the correction factor for dependence of the detector sensitivity on the beta radiation energy is required. Correction factors for dependence of the detector sensitivity on the beta radiation energy for some beta radionuclides are presented in the Table 2.1.

МКС-15Д Снегирь — Гамма-бета дозиметр-радиометр с поверкой.

Дозиметр МКС-15Д СНЕГИРЬ предназначен для работы в «грязных» условиях. Позволяет переключать режимы и проводить измерения без извлечения из защитного чехла. Измерение плотности потока бета излучения проводится с автоматическим вычитанием фона гамма излучения.

Назначение дозиметра МКС-15Д Снегирь:

• измерение мощности дозы H*(10) гамма­-излучения;
• измерение дозы Н*(10) гамма­-излучения;
• измерение плотности потока бета-частиц;
• оценка скорости счета при совмещенных измерениях гамма- и бета-излучений.

Свойства дозиметра гамма и бета излучения МКС-15Д Снегирь:

• индикация статистической погрешности в процессе измерения;
• непрерывное измерение с постоянным уточнением результата;
• автоматический перезапуск прибора при изменении мощности дозы;
• результат измерения с любой необходимой статистической погрешностью;
• компенсация скорости счета, обусловленной наличием гамма­-излучения, при измерении плотности потока бета-излучения;
• индикация единицы измерения;
• индикация разряда батареи;
• подсветка дисплея;
• возможность установки порогового уровня сигнализации по мощности дозы, при превышении которого выдается звуковой сигнал;
• технические характеристики соответствуют требованиям инструкции ЦБ РФ №131И от 04.12.2007 «О порядке выявления, временного хранения, гашения и уничтожения денежных знаков с радиоактивным загрязнением»;
• межповерочный интервал 2 года.
