The composition of claim 1, wherein the composition comprises water, nitrilotriacetic acid, hydrochloric acid, ammonium molybdophosphate, the fatty alcohol ether sulfate, sodium fluoride, potassium fluoride, and ammonium nitrate. 11. The composition of claim 1, wherein the composition comprises water, nitrilotriacetic acid, citric acid, hydrochloric acid, ammonium molybdophosphate, the fatty alcohol ether sulfate, sodium fluoride, potassium fluoride, and ammonium nitrate. 12. The composition of claim 1, wherein the pH of the composition is between about -0.5 and about 5. 13. The composition of claim 1, wherein the composition is formulated to generate a foam. 14. The composition of claim 1, wherein a pH of the composition is less than about 6. 15. A composition, comprising:water;a fatty alcohol ether sulfate;nitrilotriacetic acid;hydrochloric acid;sodium fluoride;potassium fluoride;ammonium nitrate; andgelatin. 16. The composition of claim 15, further comprising corn starch, citric acid, and ammonium molybdophosphate. 17. The composition of claim 15, wherein the composition comprises from about 0.03% by weight to about 1% by weight of nitrilotriacetic acid. 18. The composition of claim 15, wherein the composition comprises from about 20% by weight to about 35% by weight of hydrochloric acid. 19. A composition consisting essentially of:water;a fatty alcohol ether sulfate;nitrilotriacetic acid;hydrochloric acid;sodium fluoride;corn starch;citric acid;ammonium nitrate;potassium fluoride;ammonium molybdophosphate; andgelatin. 20. A method of decontaminating a surface, comprising:exposing a surface to a composition, the surface having a radioactive contaminant material thereon and the composition comprising:water;at least one acid;at least one surfactant;at least one fluoride salt; andammonium nitrate; andremoving at least a portion of the composition from the surface to remove at least a portion of the radioactive contaminant material from the surface. 21. The method of claim 20, wherein removing at least a portion of the radioactive contaminant material from the surface further comprises removing biological contaminant materials or chemical contaminant materials from the surface. 22. The method of claim 20, further comprising applying ultrasonic energy to the composition. 23. The method of claim 20, further comprising injecting a gas into the composition to produce a foam before exposing the surface to the composition. 24. The method of claim 20, wherein exposing the surface to a composition comprises exposing the surface to a composition comprising water, a fatty alcohol ether sulfate, nitrilotriacetic acid, hydrochloric acid, sodium fluoride, potassium fluoride, and ammonium nitrate. 25. The method of claim 20, wherein exposing a surface to a composition comprises exposing the surface to a composition wherein:the water comprises from about 40% by weight to about 50% by weight of the composition;the at least one acid comprises from about 20% by weight to about 60% by weight of the composition;the at least one surfactant comprises from about 0.1% by weight to about 10% by weight of the composition;the at least one fluoride salt comprises from about 0.1% by weight to about 10% by weight of the composition; andthe ammonium nitrate comprises from about 0.05% by weight to about 5.0% by weight of the composition.
