Abstract
A personal radiation and density meter system includes a housing, a radiation detection subsystem and a radiation emitting sub-system. The housing includes an interior portion configured as an interior space, and a slot. The radiation detection sub-system includes a personal radiation dosimeter positioned in the slot. The radiation emitting sub-system includes a shield assembly, a source, an actuator, a trigger, and an aperture.
Claims19
A personal radiation and density meter system, comprising:
- a housing including;
- an interior portion configured as an interior space;
- and
- a slot;
- a radiation detection sub-system including;
- a personal radiation dosimeter (PRD) positioned in the slot;
- and
- a radiation emitting sub-system including;
- a shield assembly in the interior portion and surrounding a gamma emitting element;
- an actuator in the interior portion and coupled to the shield assembly, the actuator configured under user-initiated control to move the shield assembly from a shielding configuration to an exposure configuration;
- a trigger mounted to the housing and coupled to the actuator) for one-hand control of the actuator;
- and
- an aperture defined through a wall of the shield assembly and configured to direct radiation out of the shield assembly when the shield assembly is in the exposure configuration.
