2 Compliance with this Memorandum is mandatory. To the extent its direction is inconsistent with other Air FORCE publications, the information herein prevails, in accordance with AFI 33-360, Publications and Forms Management. Change the following paragraphs: Multiple MMEs (two or more) are not authorized in enclosed spaces such as magazines or facilities where HERO SUSCEPTIBLE or HERO UNSAFE ordnance is stored or built-up, unless authorized by AFSEC/SEW; the aggregated effects on the ambient or volumetric electromagnetic field in those spaces may increase as a results of complex cavity effects.

3 If the RADHAZ survey included the use of two or more AFSEC/SEW approved MMEs while maintaining EME levels that did not exceed HERO EME levels for ordnance (HERO SUSCEPTIBLE or HERO UNSAFE), multiple MMEs are permissible. Use of multiple MMEs inside enclosed spaces is not a concern around HERO SAFE ordnance because the electromagnetic energy produced by the MMEs is unable to exceed MIL-STD-464C levels. Multiple MMEs must maintain an SSD of 10 feet from ordnance even if one or more meet the criteria of Table Table is used for TFEs/MEs if the EIRP and frequency(ies) requirements are met.

4 AFSEC/SEW uses Table when determining the appropriate SSD for MMEs. Multiple MMEs (two or more) are not authorized in enclosed spaces such as magazines or facilities where ordnance is stored or built-up; the aggregated effects on the ambient or volumetric electromagnetic field in those spaces may increase as a results of complex cavity effects, unless authorized by AFSEC/SEW. (T-1). If the RADHAZ survey included the use of two or more AFSEC/SEW approved MMEs while maintaining EME levels that did not exceed HERO EME levels for ordnance (HERO SUSCEPTIBLE or HERO UNSAFE), multiple MMEs are permissible.

5 Use of multiple MMEs in enclosed areas is not a concern around HERO SAFE ordnance because the electromagnetic energy produced by the MMEs is unable to exceed MIL-STD-464C levels. Multiple MMEs must maintain an SSD of 10 feet from ordnance even if one or more meet the criteria of Table Multiple MMEs (two or more) are not authorized in enclosed spaces such as facilities where nuclear weapons are built-up or undergoing maintenance or where nuclear weapon HERO UNSAFE components are stored, unless authorized by AFSEC/SEW; the aggregated effects on the ambient or volumetric electromagnetic field in those spaces may increase as a results of complex cavity effects.

6 If the RADHAZ survey included the use of two or more AFSEC/SEW approved MMEs while maintaining EME levels that did not exceed HERO EME levels for HERO UNSAFE nuclear weapons, multiple MMEs are permissible in enclosed spaces. Multiple MMEs (two or more) are authorized around HERO SAFE nuclear weapons or components in enclosed spaces, protective aircraft shelters or storage facilities. Each MME shall maintain a SSD of 10 feet or greater even if one or more meet the criteria of Table This memorandum becomes void after one year has elapsed from the date of this memorandum, or upon publication of an Interim Change or rewrite of the affected publication whichever is earlier.
