Furthermore, sampling and analytical measurement capacities (time, people, cost) during the early phase after nuclear emergencies need to be considered in the preparedness and action plan, and sampling and measurement exercises are highly recommended.

IAEA-TECDOC-1092 Generic procedures for monitoring in a nuclear or radiological emergency (1999) When each monitoring / research project is planned, these references are used as guidelines for site selection and for identifying things to look out for when taking samples. To enhance the efficiency of a protective response in the case of a nuclear accident, predetermined sampling points for soil and vegetation sampling should be considered in the preparedness plan for nuclear emergencies.

Consequently, vegetation sampling is recommended when the additional dose rate (above background) is higher than 0.1 μSv/h. The activity concentrations of 137Cs and 131I in weed samples measured immediately after the FDNPP accident were related to the air dose rate at 1 m.
The detailed protocols and results can provide a sound basis for guidelines of soil and vegetation sampling for nuclear emergency monitoring. In this study, the sampling protocols applied just after the FDNPP accident were reviewed, and the monitoring data were analysed.
After the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident, immediate soil and vegetation sampling were conducted according to the action plan of nuclear emergency monitoring however, analysing the monitoring dataset was difficult because the sampling protocols were not standardised.
