The absorption parameters such as total mass attenuation coeffi cients, molecular, atomic, and electronic cross sections, effective atomic numbers and electron densities were calculated for some selected enzyme inhibitors in the photon energy range from 1 keV up to 100 GeV.

Chondromyxoid fi broma (CMF) is a very rare benign cartilaginous tumor representing less than 0.5% of all bone tumors while also being the rarest cartilaginous bone tumor. Common locations of occurrence include the metaphysial region of the proximal tibia and distal femur. We report a case of a 10-year-old female affected by a CMF of the left lower tibia. The radiological features demonstrated by X-ray and magnetic resonance imaging (MRI) are discussed

The linear no-threshold hypothesis (LNT)-the basis of radiation regulatory policy-extrapolates from observed high-dose harm to assumed low-dose harm, entailing that all ionizing radiation is harmful, by denying any biological response to damage and asserting cumulative lifetime harm, regardless of dose or dose rate. All aspects of LNT are demonstrably false. There are evolved biological responses that repair or remove radiogenic damage from low doses and dose rates, thereby averting acute harm and precluding the alleged cumulative damage. LNT and its offspring, the “as low as reasonably achievable” principle, do not err on the side of caution; neither is truly conservative.
