CK Detectors – esc is a member of a consortium for R&D of ionizing radiation detection systems for applications in medical diagnostics, radiotherapy, radiation dosimetry, defectoscopy and other fields. One of deliverables is used as RPAS/UAS payload.
Ionizing radiation hardened detector
During aerial monitoring continuous sampling is carried out measuring the photon dose equivalent (PFDE), which is automatically and continuously calculated the height of 1 m above the ground. During aerial monitoring spectrometric measurements can also find surface activity of radionuclides on the ground. Aerial monitoring is performed from a helicopter flying at an altitude of about 100 m above the ground on a predetermined (waypoint selected) route.
In nominal radiation situations in the Czech Republic, aerial training activities are carried out in selected areas once or twice a year.
Aerial monitoring is one of the methods used in particular in the event of a radiological accident, where fast indicative mapping of radiation levels of the affected area and information distribution of the situation are critical (primary data are collected calculations using propagation models and real weather conditions).
Such monitoring can reduce the exposure of personnel conducting ground monitoring of radiation accidents. Its main disadvantage however, is that it is somewhat dependent on weather conditions. Aerial monitoring is currently carried out by the National Radiation Protection Institute of Sciences, and the Army of the Czech Republic.
