Abstract Measurements of biological effects arising from exposure to microwave energy are significant only when the exposure is accurately known. Significant errors (as great as 10:1) in measurements of microwave leakage energy result when densitometers currently available are used to measure microwave leakage energy within 6 or 8 inches of their source. The nature of the leakage fields which may arise in the vicinity of a microwave oven door is described in terms of four possible configurations of the leak. The relationship of the near field strength and far field strength to the principal leakage determining dimension is qualitatively described in each case. The effect of nearby objects (an instrument or a portion of a body) is also described. Based on these considerations the Association of Home Appliance Manufacturers, through its Range Standards Committee, has prepared a specification for microwave leakage detectors which will not alter the fields if the instrument is 2 inches or more away from the source - equivalent to the nose-to-eyeball distance. Newer instruments are evaluated relative to this specification. The evaluation is based upon actual test data in an idealized leakage
