My photos come out at 150 dpi after scanning (Agfa ScanWise scanner). The original images show clear colors (taken off a calendar of Mykonos); however, when viewed in Photoshop the blues (e.g. of the sea) and all other parts of the image show a sort of chequered or ‘moiré’ pattern on the monitor. I can get rid of this with a gaussian blur but of course this has the effect of unsharpening the images.

Is this a flaw in my scanner, something I am missing in the scanning process, or is this an unavoidable nuisance?

What is the best way of getting rid of it in photoshop without too much blurring of the whole image?

Any and all ideas welcome

After the built-in descreening on many scanners the easiest method is to tilt the original on the scanner. Each original has its own best angle so experimentation is necessary. Try 15 degrees first. Change your file to Lab and blur the a and be channels.
