Which of the following accurately describe film badges? A control badge is is used with each batch of badges Radiation exposure is determined by measuring film densities with an sensitometer The film densities are plotted on a characteristic curve

The categories of radiation survey instruments include: Those with a readout scale Those without a readout scale Ionization-chamber based
