Apparatus, method, and system for selectively effecting and/or killing bacteria

A method for selectively killing or destroying at least one bacteria, comprising:

• generating, with at least one ultraviolet (UV) source, at least one bactericidal radiation configured to selectively kill or destroy the at least one bacteria on or within a body, while avoiding harm to cells of the body, wherein the at least one bactericidal radiation has at least one wavelength that is in a range of 190 nanometers (nm) to 230 nm, and wherein a peak wavelength of the at least one bactericidal radiation is at least one of approximately at 207 nm or approximately at 222 nm;
• filtering, with a filter arrangement comprising at least one of a band pass filter or a combination of a low pass filter and a high pass filter, the at least one bactericidal radiation to prevent all UVC wavelengths that are outside of the range from passing through the filter arrangement;
• allowing all wavelengths in the range of 190 nm to 230 nm to pass through the filter arrangement and be provided to the body;
• and
• irradiating the at least one bacteria using the allowed wavelengths and selectively killing or destroying the at least one bacteria.

An apparatus for killing or destroying at least one bacteria, comprising:

• at least one ultra-violet (UV) source configured to generate at least one bactericidal radiation configured to kill or destroy the at least one bacteria, wherein the at least one bactericidal radiation has a peak wavelength provided in a range of 190 nanometers (nm) to 230 nm;
• and
• at least one filter arrangement configured to:
• (i) prevent all UVC wavelengths that are outside of the range from passing through the at least one filter arrangement, and (ii) allow wavelengths in in the range of 190 nm to 230 nm to be pass through the filter arrangement and be provided to the body,
• wherein the at least one filter arrangement is configured to modify the at least one bactericidal radiation to penetrate and damage, kill or destroy the at least one bacteria.
