Many people are not aware that human respiration contributes significantly to elevated indoor CO2 concentrations. Ambient CO2 levels outside are approximately 395 PPM. (this level fluctuates throughout the day / year, but is usually within 10-20ppm of baseline). When people are indoors, the exhaled CO2 does not disperse outdoors fast enough and accumulates within the building.

We've been testing the new Aretas Wireless Radiation sensor in Mackenzie BC which is in Northern Canada. We have been performing radiation detection and measurement testing indoor and outdoor ambient levels and doing spot tests throughout the area. Aretas's new sensor primarily detects beta, gamma and x-rays (some sensitivity to alpha sources has also been tested, but is not offered at this time). The general detector sensitivity is 5.9 cpm/μSv/h. The sensor also features internal temperature compensation and linear response over a wide temperature range (-30C to +50C).

It is well established that forest fires can contribute significant amounts of CO2 and particulates (as well as other combustion byproducts) into the atmosphere. However, high baseline atmospheric CO2 levels are commonly associated with high population areas such as cities (which have high amounts of vehicle traffic and industrial emissions).

Hog Fuel Pile Fires are a relatively common occurrence in the mill and biomass fuel industries (as well as any industry that stores and maintains hog piles). Hog Pile Fires are difficult to extinguish and are extremely costly. Part of the predicament in preventing hog fuel pile fires is due to the fact that the internal temperature of the pile can reach combustion temperatures via composting effect alone and there are few external signals visible prior to combustion.

Carbon dioxide (CO2) is a naturally formed chemical compound, partly responsible for the greenhouse effect and is considered the most important human-contributed greenhouse gas. [1] Human activities have altered the global carbon cycle in the past centuries and human emissions of carbon dioxide into the atmosphere have exceeded natural fluctuations.

We recently had a very happy client contact us to share a great success story using our ice arena solution.
Monitoring at a Steamboat Springs, CO ice arena protected employees and the public from high Carbon Monoxide and Nitrogen Dioxide levels. The Howelsen Park Ice Arena received a notification of high-levels of CO exceeding 120 ppm.

It occurred to me when staying at a hotel recently, that I never gave consideration to hotel indoor air quality. I instead, swayed by the potential for entertainment, chose a hotel based on its services and amenities. I reviewed the hotel online and asked friends that had stayed there about their experience and in retrospect, was given quite accurate information. The hotel indoor environment was sub-par but the amenities were second to none for the area.

I was reading a recent article on the USA Today website which highlights the effects that higher energy costs have on pushing up wholesale prices. Though the article focuses on the 0.3% increase in one month, the lesson is that energy costs are eroding buying power and slowing economic growth. The article further states that "A weak economy has contained inflation.

“Carbon monoxide (CO) gas is one of the most widespread and dangerous industrial hazards. It is the most common cause of occupational gas poisoning leading to death. It can be lethal at concentrations as low as 1000 parts per million (ppm).” WorkSafe BC. (1) Unintentional CO exposure accounts for an estimated 15,000 emergency department visits and 500 unintentional deaths in the United States each year. (2)
