Radioactive Sealed Source Leak Testing

State of Ohio Department of Health licensed and approved leak test kit and procedure for leak testing of alpha, beta, and gamma emitting sources.

We can leak test several types of sources including industrial gauges and laboratory instruments.

Measurements are made on state-of-the-art liquid scintillation counter and are traceable to NIST (formerly NBS) standards.

Services Provided:

Reminder letter sent one month before next test is due

Record sheet for required source check and inventory

Leak test certificate indicating when leak test was performed and results of test

Computer database of test results maintained for each client and each source

Leak test performed by trained personnel

Analysis Services

Radiation Area Wipe Analysis

Area wipes are analyzed by liquid scintillation counting.
Measurements are traceable to NIST standards.

Radioactive Sample Analysis

Known or unknown isotope analysis of samples by liquid scintillation counting, gamma ray spectroscopy, or gas proportional counting.
Samples can be solids, liquids or gases.
Results are traceable to NIST standards.

NORM Analysis

Measurements are made by gamma ray spectroscopy which are traceable to NIST standards.
