How much resources are reasonable to spend on radiological protection?

In short terms, a society's available resources are finite and must be prioritised. The more resources that are spent on radiological protection, the lesser resources are available for other needs. The ALARA principle states that exposure of ionizing radiation should be kept as low as reasonably achievable, taking into account economic and societal factors.

Cross-cultural adaptation and validation of the Swedish version of the Modified Dental Anxiety Scale.

Introduction: The impact of dental anxiety is profound. At the same time, dental anxiety is sometimes difficult to detect. Therefore, a patient-reported outcome measure is needed.

Effects of Ring Opening and Chemical Modification on the Properties of Dry and Moist Cellulose─Predictions with Molecular Dynamics Simulations.

Thermoplastic properties in cellulosic materials can be achieved by opening the glucose rings in cellulose and introducing new functional groups. Using molecular dynamics, we simulated amorphous cellulose and eight modified versions under dry and moist conditions. Modifications included ring openings and functionalization with hydroxy, aldehyde, hydroxylamine, and carboxyl groups.

Melt processing of chemically modified cellulosic fibres with only water as plasticiser: Effects of moisture content and processing temperature.

To replace petroleum-derived polymers with cellulose fibres, it is desirable to have the option of melt processing. However, upon heating, cellulose degradation typically starts before the material reaches its softening temperature. Alternatives to plastics should also, ideally, be recyclable via existing recycling streams.
