Effective surface contamination

The HF-4 series of hand-foot contamination monitors are intended for the measurement of surface contamination by alpha, beta and gamma emitting radionuclides on hands, feet and clothing. The monitor uses two hand and two feet scintillation detectors. For proper contamination checks, hands must be measured in two steps, palms and backs separately. Optionally, the right hand detector can be equipped with a handle and used as a frisking probe.

Applications

  • Nuclear Facilities
  • Waste Management
  • Nuclear Medicine
  • Ionising Radiation Metrology

Types

HF-4A

The HF-4A measures only alpha contamination and is therefore designed especially for plants used for the production and/or processing of nuclear fuel and uranium mining. It has suppressed sensitivity to gamma radiation and thus low response to gamma background.

HF-AB

The HF-4B measures alpha and beta contamination but cannot discriminate them. It has the highest sensitivity to beta contamination, especially low energies. It is suitable for nuclear power stations, where the gamma background may be increased or variable. It has suppressed sensitivity to gamma radiation and thus low response to gamma background.

HF-4C

The HF-4C is a two-channel monitor, which can distinguish between alpha and beta contamination. It is suitable for nuclear power stations, where the gamma background may be increased or variable. It has suppressed sensitivity to gamma radiation and thus low response to gamma background.

HF-4D

The HF-4D measures all types of radiation (alpha, beta, gamma) in one channel. It is suitable for nuclear medicine workplaces where Tc-99m and possibly other pure gamma emitters are used. It has increased sensitivity to gamma radiation and thus higher response to gamma background.

HF-4E

The HF-4E measures all types of contamination and can discriminate alphas. It is suitable for training or experimental workplaces. It has increased sensitivity to gamma radiation and thus higher response to gamma background.
