The ERiS2-M/G monitor is a versatile instrument for radiation detection and measuring, thanks to its features, its variety of detectors and accessories.

• Interchangeable external probes for contamination and radiation detection.
• Compatible with probes of MS6020 multisonde monitor .
• Recognition of the probes and their parameters (alarms, factors, etc).
• Rate mode and counter mode with configurable time limit.
• Measure freeze and search mode.
• Compact, Portable and Lightweight.
• Self-diagnosis with alarm indication, detector failure, battery level and saturation of the measuring range.

In orther to adapt to any application, there is a complete set of radioactive contamination probes (Alpha, Beta, Gamma) and radiation (Beta, Gamma, X-rays) with different types of detectors (Geiger-Müller, proportional, scintillation), and different measurement ranges and energy ranges.

The ERiS2 is fully compatible with the probes used by the MS6020 multisonde monitor. The exchange of probes is very simple . When switched on, the ERiS2-M recognizes the probe and automatically applies its parameters, calibration factors, alarm thresholds, etc.). Any change of the parameters is stored in the probe itself so it can be used with any other ERiS2-M/G monitor. Contamination probes have a library of 7 totally free isotopes in which the user can configure all parameters.

A complex calculation system performs all the necessary operations, applying the corresponding factors and parameters, for the conversion of the detected events to the scientific unit (cps, Bq, Bq/cm², µSv/h, µSv) that the user selects. In addition, it applies the dead time correction characteristic of some detectors, as well as the background subtraction for the activity units (Bq and Bq/cm²).

The ERiS2 continuously checks the alarm levels, the battery level, the status of the probe, etc., and it immediately reports any incident or anomaly.

The ERiS2 allows different types of measurement depending on the application. The rate mode has a dynamic time constant, that is, the counting time is fixed as long as the deviation does not exceed 3 times the standard deviation of the mean, in which case, an automatic update of the measurement will occur. This means that the measurements are stable but that, in case of a significant change in radiation level, the response of the meter is very fast.

With contamination probes and for measurements with a fixed and prolonged time (smear measurements, calibrations, etc.), the equipment has the counter mode in which the user can set the counting time.

Another interesting function is the search mode, which shows a graph indicating the pulses detected with a small time constant of 5 seconds, so that it allows to see the detected events in an intuitive way while performing, for example, the scan of a surface.

The ERiS2 can save the measurements . The records include the date, time, measurements, unit, etc. It can save manually, or automatically with configurable sampling times. The ERiS2-G model, with built-in GPS, also allows recording the measurements together with the geographical coordinates. With a simple software the user can download data and storage them on a PC.

There is also a wide variety of optional accessories that allow the ERiS2 to adapt to different applications.

ERiS2-M/G Multiprobe Radiation and Contamination Monitor - Brochure in English

¿En qué se diferencian la medida de la radiación y la medida de la contaminación radiactiva?

Se habla de medida de radiación cuando nos referimos al nivel de radiación ambiental, normalmente gamma o RayosX, usando la unidad del Sistema Internacional, Sievert por hora. Sin embargo, en la medida de contaminación nos referimos al nivel de radiactividad superficial de un emisor alfa, beta o gamma. Este último es el apropiado para chequear superficies a corta distancia, ya que, dependiendo del emisor, el alcance en aire puede ser de milímetros o centímetros.

¿Por qué el Eris1D lleva un filtro en la ventana del detector?

Antes de nada hay que indicar que los detectores tipo Geiger de ventana tienen curvas de respuesta que varían significativamente dependiendo de la energía de la radiación detectada. Esto significa que para diferentes energías se necesitan diferentes coeficientes de calibración. Es por ello que cuando en el Eris1D el filtro está posicionado tapando la ventana tiene dos importante funciones. En primer lugar, atenúa las energías de los fotones, de forma que con el ajuste de calibración de fábrica realizada para el emisor de Cs-137, se garantiza que las medidas en el display van a estar en un rango de +/-20%, independientemente del emisor gamma o de RayosX. En segundo lugar, se garantiza que no está midiendo ningún emisor alfa ni beta, por lo que se tiene la certeza que el valor en pantalla corresponde a emisores gamma, y por tanto, no alteran de alguna forma el valor medido.

¿Es fácil cambiar de un modo de medida al otro?

Es muy fácil. Para pasar de medir contaminación a radiación, o viceversa, tan solo hay que girar manualmente el filtro y el Eris1D lo detecta automáticamente y cambia la unidad de medida y aplica el factor correspondiente (en el caso de la radiación).

¿Cuando es apropiado medir con la ventana abierta o cerrada?

Si lo que se desea es medir el nivel de radiación ambiental, se debe medir con la ventana tapada. Si lo que se desea es chequear una superficie que se cree contaminada, o buscar posibles fugas, lo mejor es hacerlo con la ventana abierta y lo más cerca posible para detectar posibles emisores alfa, beta o gamma.

¿Por qué se calibra en Cesio 137?

Los detectores de este tipo tienen un rango de medida que va de varias decenas de KeV (kiloelectrón-voltio) a 1.2-2 MeV (Megaelectrón-voltio). El Cesio-137 es un emisor gamma principalmente, cuya energía de emisión es de 660 KeV, es decir, aproximadamente en la mitad del rango de medida de este tipo de detectores. Por eso, se adopta internacionalmente como el radioisótopo ideal para ajustar y calibrar este tipo de intrumentos para la medida de la radiación ambiental.

¿Qué significa H*(10)?

Es una nomenclatura internacional que hace referencia a la Dosis Equivalente Ambiental, cuya unidad del Sistema Internacional es el Sievert. Por eso, el Eris1D es calibrado en esta magnitud y muestra la medida de radiación en esta unidad (en uSv/h, o en mSv/h).

¿Es muy delicada la ventana del detector?

Todos los detectores de ventana abierta tienen una membrana muy fina permitiendo la detección de las partículas alfas y emisores beta y gamma de baja energía, pero con el inconveniente de que es muy delicada. Por ello, además de la protección del propio filtro, la ventana del Eris1D está protegida por una rejilla con un 80% de transparencia. No obstante, se advierte que no se debe introducir ningún elemento a través de la rejilla.

¿Que diferencias hay con el Eris1R y el Eris1C?

El Eris1D es una mezcla de los modelos Eris1R y Eris1D. El Eris1R es específico para la medida de la radiación ambiental gamma mientras que el Eris1C es específico para la medida de la contaminación radiactiva alfa, beta y gamma. El Eris1D permite los dos tipos diferentes de medida pero con algunas limitaciones en sus prestaciones. Por ejemplo, en la medida de la radiación, el rango de medida es menor y no dispone del valor de la dosis acumulada, como tiene el Eris1R. En cuanto a la contaminación, no dispone de una librería de isótopos y de la unidad de Bq/cm2, como si dispone el Eris1C. En la pestaña de "Productos Relacionados" o "Comparativa" se pueden ver las diferencias entre los 3 modelos.
