Claims
- 59. A method of decontaminating a contaminated non-conducting surface, the method comprising:
providing a conducting backing for the non-conducting surface; spraying photosensitizer onto the contaminated surface, the photosensitizer being electrically charged so that it is attracted to the contaminated surface; and illuminating the sprayed surface with light.
- 60. The method according to claim 59 wherein the light includes light of wavelengths between about 200 nm and about 320 nm.
- 61. A system for decontaminating a contaminated surface, the system comprising:
an apparatus for spraying a photosensitizer on the surface; a light source for illuminating the sprayed contaminated surface; and a temperature control system for heating said photosensitizer with waste heat from said light source.
- 62. A method for decontaminating the surface of a contaminated object, the method comprising:
surrounding the contaminated object with a portable barrier; spraying an electrically charged photosensitizer onto the object, the photosensitizer being charged so that excess photosensitizer is attracted to and deposits upon said portable barrier; illuminating the sprayed surfaces of the object with light.
- 63. The method according to claim 62 wherein the barrier is electrically charged to attract the electrically charged photosensitizer.
- 64. The method according to claim 62 wherein the barrier is grounded to attract the electrically charged photosensitizer.
- 65. The method according to claim 62 wherein the light includes UV light.
- 66. The method according to claim 65 wherein the barrier is substantially opaque to UV light.
- 67. A method of decontaminating the surface of a contaminated object, the method comprising:
surrounding the contaminated object with a barrier having an entrance and an exit therein; establishing an air flow into the exit and out of the entrance; spraying a photosensitizer onto the surfaces of the object; and illuminating the sprayed surfaces of the object with light.
- 68. The method according to claim 67 wherein the light includes light of a wavelength of between about 200 nm and about 320 nm.
