beam on indicators are located

control panel, entrance door, on the treatment unit

types of shielding

bratty (lead shield), x-ray (lead apron), testicular shield

TJC requires

- annual education of staff in dose reduction techniques - minimum qualifications for medical physicists - documentation of CT radiation doses - management of CT protocols to minimize radiation dose

2 objectives of radiation protection

- prevent clinically important radiation induced harm - limit the risk of radiation induced cancers

effective radiation safety program must include

-Employers responsibility: Necessary resources to implement ALARA Appropriate environment for ALARA program Written ALARA policy statement identifying commitment to keep all employees within ALARA standards Perform periodic exposure audits to determine how to lower radiation exposure in the workplace -Radiation Workers Responsibility: Beware of rules governing the workplace Perform duties consistent with ALARA principles

diagnostic efficacy

Is the degree to which the diagnostic study accurately reveals the presence or absence of diseases Efficacy determines whether an imaging procedure or treatment is needed or justified

RSNA

Radiological Society of North America

image wisely campaign

address concerns about the increase in public radiation exposure from medical imaging. objective is lowering the amt of radiation used in necessary studies & eliminating unnecessary

radiation protection

is defined as the effective measures employed by radiation workers to safeguard patients, personnel and the general public from unnecessary exposure to ionizing radiation.

Why do we need to limit the amount of radiation exposure we receive?

radiation can cause harmful biological effects, damage living tissue, radiation induced cancers

RSO

radiation safety officer - execution, enforcement, maintenance

risk

risk after irradiating and is viewed as the possibility of inducing a - radiogenic cancer - genetic defect possibility of inducing adverse biological effects

goal of radiation

to prevent the occurrence of serious radiation-induced conditions
