Table 1 Parameters of the function used to model the relationship between equivalent dose rates measurements \({(H}_{T})\) and positions of the point source \((s)\)

Regression parameters			Goodness of fit
\({H}_{T}\left(s\right)=a.{\sqrt{{s}^{2}+{b}^{2}}}^{c}\)			\({R}^{2}\)	\(\mathrm{RMSE }\,({\upmu\,{\mathrm {Sv}} }\,{\mathrm{h}}^{-1})\)
\(a\,({\upmu {\mathrm{Sv}} }\,{\mathrm{h}}^{-1}\, {\mathrm{cm}}^{-c})\)	\(b\) (cm)	\(c\)	\({R}^{2}\)
516.4	4.065	− 1.917	0.9994	0.267

Two goodness-of-fit criteria are additionally provided for each regression: the coefficients of determination (\({R}^{2}\)) and the root mean square error (RMSE)
