Scanning Electron Microscopy

Scanning Electron Microscopy

A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

Summary

This summary is machine-generated.

Radiological surveys of metal tanks require careful data interpretation. Misinterpreting scan data (counts per minute) versus direct measurements (disintegrations per minute per 100 cm) can lead to project delays and increased costs.

Area of Science:

Environmental Science
Nuclear Engineering
Radiation Protection

Background:

Radiological surveys are crucial for the disposition of surplus materials.
Site-specific free release limits, such as 5,000 disintegrations per minute per 100 cm (dpm 100 cm), guide disposition decisions.
Radon progeny buildup on oxidized metal surfaces can impact radiological measurements.

Purpose of the Study:

To detail the radiological survey process for a surplus metal tank.
To highlight potential misinterpretations of radiological data, specifically scan data versus direct measurements.
To emphasize the importance of clear communication regarding data interpretation and measurement implications.

Main Methods:

Performing radiological surveys including radiation scans and fixed-point measurements.
Utilizing data loggers to record scan data at 1-second intervals, reported in counts per minute (cpm).
Collecting quantitative direct measurements in dpm 100 cm for comparison with site limits.

Main Results:

Scan data (cpm) and direct measurements (dpm 100 cm) were both reported for completeness.
A stakeholder misinterpreted scan data by converting it to dpm 100 cm using instrument efficiency and background data.
The converted scan data frequently exceeded the site's free release limit, causing disposition delays.

Conclusions:

Proper communication regarding the use and interpretation of radiological scan data is essential.
Understanding the implications of radon progeny buildup on oxidized surfaces is critical for accurate assessments.
Avoiding data misinterpretation can prevent unnecessary project delays and additional costs in radioactive material disposition.
