Water samples from 44 monitoring wells at three military installations were analyzed for the high explosives TNT and RDX using immunoassay test kits. The accuracy and precision of the kit determinations were compared with results obtained using the RP-HPLC, EPA Method 8330. Most of the kits achieved a +50% relative percent difference criterion over 85% of the time. One of the kits failed this test over half the time. Careful consideration must be given to interferences that may be present and...

Theoretical and experimental studies of planar detonation waves in Amatex 20 were performed to obtain a better understanding of the role of ammonium nitrate in the detonation process in explosives formulated from RDX, TNT, and AN. The theoretical work was performed to provide a more definitive and realistic treatment of steady-state detonation waves in such composite explosives. The treatment developed for such waves extends the classical Zelodovich-von Neumann-Doering (ZND) model for ideal...

The effects of water in close contact with detonating high explosives have been studied in several test series and it has been determined that water has a mitigation effect on the blast wave from an explosion. Both maximum overpressure and impulse density will be reduced. The effective charge size can be reduced with more than 50%, possibly as much as 80%. This means that possible equivalence factor is 0.2 (amount of high explosive with/without water giving the same effects). It has been...

The Russian designed MC-1 ultrahigh magnetic field generator was tested in 5 experiments as part of a joint US-Russian collaboration at Los Alamos National Laboratory in December of 1993. The standard Russian explosive (50/50 RDX/TNT) was replaced with higher-energy-density US explosive, either Comp-B (60/40 RDX/TNT) or PBX-9501. Generator performance with COMP-B was nominally the same as reported for experiments with the slightly lower-energy Russian explosive. The Comp-B experiment produced a...

The detonation of military line charges is being considered as a means to clear battlefields of implanted pressure-sensitive antitank mines.. Such charges have an undesirable characteristic, however, in that, for distances less than about 1 m from the line charge, phase duration of the positive overpressure is too short to detonate the mines. This region in which mine clearance may not occur is called the skip zone.... Line-Charge Effects, Mine Clearance, Skip Zone, Airblast, Hydrodynamic...

One hundred twenty-one model tests of explosion induced craters in dry sand were conducted using small charges of PETN detonated at accelerations between 1g and 101g; ninety-six were found to be useful in analysis. Extrapolation to prototype dimensions indicates that for half-buried charges, crater volume, V, is a function of explosive weight, W to the 0.84 power, and crater radius and depth are functions of W to the 0.28 power. There were no detectable acceleration related scale effects from...

The principal objective of this work is to intensify and tailor the detonation wave output of condensed high explosives (HE's) through the use of electromagnetic energy coupling (EMEC) or augmentation. This results in the enhancement of the explosive's energy release properties. The reasons for studying EMEC phenomena in a detonating explosive are to improve the safety, performance and understanding of explosives. The technique would allow the use of low performance, yet safe explosives, in...

Blast wave phenomena include reactive and two phase flows resulting from the motion of chemical explosion products. When the blast wave interacts with structural surfaces (external discontinuities), multiple reflections and refractions occur from both external and internal discontinuities.

Raman-based spectroscopy is potentially militarily useful for standoff detection of high explosives. Normal (nonresonance) and resonance Raman spectroscopies are both light scattering techniques that use a laser to measure the vibrational spectrum of a sample. In resonance Raman, the laser is tuned to match the wavelength of a strong electronic absorbance in the molecule of interest, whereas, in normal Raman the laser is not tuned to any strong electronic absorbance bands. The selection of...

Storage and transportation of high explosives gives headaches to many logistics managers, especially when it comes to forwarding of smaller quantities, such as samples. Air transport is limited to 1.4 explosives on cargo aircraft and as 1.4S classified explosives on passenger aircraft. Most samples cannot be transported by air. Ocean transport is feasible, but due to stowage and segregation regulations in the IMDG code, as well as Port restrictions, this is an expensive solution. DGM has found...

The detonations of a high explosive in contact with a metal plate can cause the plate to spall or fracture. In order to quantitatively describe the phenomena a one-dimensional model of the H. E. plate system is assumed. The problem is then analyzed in terms of the interactions of compression and rarefaction waves. Quantitative predictions of spall using the one-dimensional model are compared to experiment and the agreement is found to be good.
