A Normally distributed random variable with mean [mu] has a probability density function given by
[gamma]/2 Pi *sigma exp(-gamma^2/sigma*x-[mu]^2/2).
Its standard deviation is given by:

Sorry but I can't make sense of the expression you have posted for the pdf.
If it's a normal distribution then it has the usual form found here: Normal distribution - Wikipedia, the free encyclopedia
So unless you can re-post a clearer expression I suggest you read the link, fit your pdf to the normal pdf given in the link and then read off what the variance and hence standard deviation is.
