Proposed Changes to Colorado Radiation Regulations: Introduction

On 5/31/18, the CDPHE announced that there are proposed changes to the radiation regulations. This happens every couple of years, and many times the changes are just housecleaning and there are not any significant differences in the works. That is not the case this time. I had planned on laying out these changes for you…

Quality Control for CR and DR Systems: Interpretation of State Regulations

The Colorado regulations spell out three distinct types of areas of quality control (QC) for computed and digital radiography systems (CR and DR, respectively). The specific regulations can be found in sections 6.3.3.2 (3), 6.3.5.7, and 6.3.5.8 in the 6 CCR 1007-1 Part 06. Here’s a summary of the regulations that are relevant for most of…

Monitoring Radiation Dose: Dosimeters and Monitoring Staff Radiation Dose

In Colorado, all facilities with x-ray equipment must have a radiation safety program. This often includes personal dosimetry badges for staff to wear. These devices are sometimes referred to as film badges, from a time when the dosimeters actually contained little pieces of x-ray film. These pieces of film would then be developed every few…

Radiation Exposure: Effects of Low-Level Radiation Exposure on the Human Body

It has been proven that high levels of radiation are bad for the human body. However, scientists are unsure whether low levels of radiation dosage are really harmful to us or not. Humans are exposed to low levels of radiation all the time, just by virtue of living on earth. We know that the human…

Radiation Protection: The Importance of Understanding the Three Basic Components to Radiation Protection

There are 3 basic components to radiation protection: Time, Distance and Shielding. Time. Dose from ionizing radiation is directly proportional to the amount of time a person is exposed to that radiation. For staff who work around radiation frequently, reducing exposure time can be accomplished in many different ways. The most obvious is just reducing the…
