1. A multiple use dosimetry apparatus comprising:

  • a pressure sensor capable of detecting a blast pressure waveform disposed in a housing;

    a cover configured to permit blast compression waves to pass through, the cover which extends out and away from the housing is seated over the pressure sensor and comprises a mesh structure comprising a particle filtering mesh layer configured to exclude dust seated against a structural mesh layer configured to provide structural integrity to the particle filtering mesh layer, wherein the structural mesh layer comprises larger mesh openings than the mesh openings of the particle filtering mesh layer in a manner that protects the pressure sensor and the particle filtering mesh layer from physical damage; and

    a dosimetry processing device with a memory coupled to the pressure sensor in the housing, the dosimetry processing device configured to execute programmed instructions stored in the memory comprising obtaining readings from the pressure sensor, storing the readings when obtained, conducting an analysis based on the obtained readings and outputting at least one of the stored readings or the conducted analysis, wherein the pressure sensor combined with the cover provides multi-directional sensitivity to blast direction and will detect the same pressure waveform independent of the relative orientation of the pressure sensor to the pressure front of the explosive blast to within fifty percent of the pressure waveform amplitude.
