Erratum to: Assessment of NORM at diamond cement factory and its effects in the environment

Erratum to: J Radioanal Nucl Chem (2011) 287:87–92 DOI 10.1007/s10967-010-0844-6

1. Equation 3: The correct equation

$$ D\, = \,0.666A_{\text{Th}} \, + \,0.429A_{\text{U}} \, + \,0.042A_{\text{K} } $$

(3)

where 0.666 Sv Bq⁻¹ is the dose constant for ²³²Th, 0.429 Sv Bq⁻¹ is the dose constant for ²³⁸U, 0.042 Sv Bq⁻¹ is the dose constant for ⁴⁰K and A _K, A _U and A _Th are the specific activities of K, U and Th, respectively.

2. Table 3: pH values corrected as shown in the table below

Table 3 Activity concentrations (Bq/kg) and the average annual effective doses (Sv/year) of ²³⁸U, ²³²Th, ⁴⁰K in the water samples with the respective average values

Thus, Fig. 2 will also change as such.
