Discovered in 1901 by Henry Becquerel, radioactivity is a natural phenomenon whose properties are now used in many fields, both civilian and military.
The role that radioactivity could play in medicine was recognized early on:
- for therapeutic purposes (radiotherapy);
- for diagnostic purposes (radiography, scanner, scintigraphy);
- for equipment sterilization.
In industry, where it is best known, radioactivity is used to generate electricity in nuclear power plants. It is also used for industrial radiography.
It is widely used in agronomy (food sterilization) and research (dating, tracing). Until recently, radioactive elements were used in smoke detectors and lightning conductors.
The harmful effects of ionizing radiation from radioactivity (α, β, γ and X) and of its widespread use call for advanced protective measures, during intervention in nuclear power plants in particular. Thus, it is the duty of companies and industries using it to define measures and procedures to ensure the protection of workers, the public and the environment. This is radiation protection.
With over 30 years’ experience in the design and manufacture of measurement solutions, particularly in the field of radiation protection, Carmelec offers a wide range of equipment for measuring and quantifying radioactivity:
- radiation survey meters;
- contamination survey meters;
- probes;
- beacons and signals.

Radiation Survey Meters
Radiation survey meters are devices intended to monitor and measure the ambient dose equivalent rate H*(10) . They are designed for ambient measurement, radiological monitoring and hot-spot detection. Perfectly suited to measuring γ and X- rays, Carmelec radiation survey meters cover a wide range of dose rates (from 0,5 µSv/h to 100 mSv/h) and applications.
Carmelec Dolphy Evolution
Dolphy Evolution is the nuclear industry benchmark radiation survey meter. It has been providing professionals with support for over ten years and is highly regarded for its measurement reliability, ease of use and readability. This radiation survey meter can be inserted into a balise SAG-A for stationary use, or for measurement reporting and monitoring.
Carmelec Dolphy Nano
Designed for lower dose rates, the Dolphy Nano is the ideal radiation survey meter for Radiation Safety Officers (RSO). It enables easy and reliable measurements of the radiological environment and can be used for hot-spot identification and zoning inspection.
Carmelec Neo Radiation Survey Meter
Thanks to its low-frequency radio communication, the NEO radiation survey meter enables measurement to be reported remotely and wirelessly. It is specifically suitable for the remote control, protection and monitoring of workers during high-risk operations.
Contamination Survey Meters
Contamination survey meters are devices intended for detecting and measuring point like or surface radioactive contamination. They are used along with portals to detect contamination on personnel and equipment leaving contaminated areas as rapidly as possible. They also reduce potential skin dose.
They help ensure that contamination is not dispersed and contribute to radiological cleanliness. In addition to the standard β contamination survey meters (Dolphy Bêta et Dolphy Frottis), Carmelec offers a contamination survey meter for measurements in high and fluctuating γ-environments (ECHO), making it possible to take measurements inside reactor buildings.
Gamma Radiography Inspection
Gamma radiography inspection is a non-destructive testing method intended to verify weld quality or to highlight weaknesses in mechanical parts. This technique requires the use of a high activity γ source.
Carmelec offers a wide range of devices to support you safely during the implementation of this complex work:
- Source Exposure Warning Beacon (Sentinelle 360 and Fixed Threshold Sentinelle 360) ;
- Gamma Radiography Information Pannel;
- LED Precaution Signs;
- Gamma Radiography Camera System Carrier.
Count Rate Meter and Associated Probes
Carmelec has developed a range of probes for the detection and measurement of surface contamination.
ICTO probes (SAI, SBI, SBMI, SXI and SGI) are intended for dismantling operations, source control or direct or smear contamination ou par frottis (α, β, β mous, γ et X). ). These probes connect to a versatile count rate meter.
Carmelec also offers probes for measuring γ and X equivalent dose rate (SI-GAM) connectable to the SAG-A or CERBERE beacons.
