Claim 17:
18. A method comprising:
disposing a downhole tool into a borehole created in a subsurface formation, the downhole tool comprising:
a collar;
a gamma ray detector positioned within the collar, the gamma ray detector to detect an electromagnetic radiation from a geological formation into which a borehole is formed and where the downhole tool is to be positioned;
a cover in opening of the collar, the cover positioned between the gamma ray detector and the geological formation, wherein the cover comprises materials that attenuate electromagnetic radiation;
a window cap positioned in a window in an opening of the cover and comprising a material capable of allowing gamma ray transmission therethrough; and
a window core positioned behind the window cap relative to an external environment of the downhole tool, wherein the window core is positioned between the window cap and the gamma ray detector;

emitting gamma rays into the subsurface formation;
receiving the gamma rays from the subsurface formation by the gamma ray detector through the window; and
detecting, by the gamma ray detector, the gamma rays from the subsurface formation.
