A material density radiological measurement system is provided. The system comprises a material density radiological detector, a squaring circuit connected to the output terminal of the detector, a constant multiplying circuit connected to the output terminal of the squaring circuit, and a subtracting circuit connected to the material density radiological detector and the constant multiplying circuit. The system eliminates the nonlinearity of the relationship between the ionization current and the density of tobacco during a measuring operation of tobacco density of a cigarette.
