- W81073 abstract "New York Telephone and Harvard University routinely monitor video display terminals as part of employee education or office design projects. Measurements are made with sensitive geiger end window or pancake detectors at the screen surface. In previous years all measurements indicated no difference from background levels in the occupied space. Recently, some newer VDTs were found to have measurable levels consistently above normal background at the screen surface. A gamma spectral analysis was made of one of the VDTs using a high resolution Ge-Li gamma ray detector coupled to a multi-channel gamma ray spectrometer. A slightly elevated potassium-40 level was detected and it was hypothesized that the potassium-40 was contained in the glass of the screen surface. The authors recommend that VDTs should be surveyed with the unit turned off to determine if the source of elevated readings may be in the glass. They also recommend expert advice in determining the proper radiation monitoring instrumentation for use in making these measurements." @default.
