A dosimeter is an instrument that measures the amount of hazardous material to which something or someone has been cumulatively exposed. The most common is the radiation dosimeter, which measures a person's or object's exposure to radiation.

How do you prepare for an atomic bomb attack?

I live in a city of about 60,000. There were five air raid sirens on roofs of large buildings around town when I was a kid, and they used to test them at noon every Tuesday. A very eerie sound. There were yellow and black Civil Defense signs in many public buildings, directing people to the basement in the event of an air raid. Food, water and blankets were supposed to be stored in these air raid shelters too, and medical supplies, including morphine, until the junkies broke in and stole the morphine. We used to have "air raid drills" when I was in elementary school. Sometimes we'd go out in the hallway and sit down on the floor with our backs to the walls, other times we'd all crowd into the "big room", which was a windowless room at the front of the lower level of the building, below ground level on that end. When I was young I worked in the Greyhound Bus Station and found an old yellow and black Civil Defense Geiger Counter in the ravaged remains of what had been the "bomb shelter" in the basement of the Bus Station. New in the box. I took it home, and later donated it to the physics lab at the local university. They did not have a Geiger Counter ("Radiological Dosimeter"). Lots of Americans dug air raid shelters in their backyards in the 50s, and you could go to places like Sears and buy a prefab unit to bury out back. And not any of this would have been the least little bit of help. All the crowding into public air raid shelters would have just made it easier to find the corpses afterward. Somewhere in my childhood they stopped testing the air raid sirens every Tuesday. The government had said we were a Class II nuclear target, due to our proximity to other high priority targets, and the fact that most Russian missiles had ten separate warheads - each its own bomb - which had to be dispersed in a radius of less than four hundred miles. Ballistic missiles fly about six thousand miles an hour, so they said we could expect twenty minutes warning, at the most, before the detonations. You would not be able to get anywhere. You cant get out of town in twenty minutes when the roads aren't clogged with people trying to flee for their lives. When I was about twenty, one Saturday morning, as I lay hungover in bed, some fool said "Hey, what's this" and pushed the button that activated the air raid sirens, which had not been tested for several years, and never on a Saturday. I half woke, decided that twenty minutes was not going to do me much good from where i was, and decided to die in bed. So, how to prepare. Here's what we told one another: put your head between your legs, and kiss your butt goodbye.

Is a dosimeter a radiation badge that contains a sensitized film?

A dosimeter based on sensitized film is one kind of radiation dosimeter, but there are other different kinds, and film badges are becoming less common. One widely known dosimeter is the direct read "pen style" electroscope dosimeter. Another "pen style" dosimeter is a miniature ionization chamber, but like the film badge dosimeter requires special equipment to read it later in a lab. Probably the most commonly used type of dosimeter outside of emergency response is the TLD, or thermoluminescent dosimeter.

Who invented the radiation dosimeter?

The radiation dosimeter was invented by Werner Forssmann and Burchard B. Harned in the 1920s. They developed the first wearable dosimeter to measure radiation exposure in workers.

What does a dosimeter alarm indicate?

Why would a pilot wear a film badge dosimeter?

A pilot would wear a film badge dosimeter to monitor their exposure to radiation during flight. This device measures the amount of radiation the pilot is being exposed to and helps ensure they are not exceeding safe radiation levels. Regular use of the film badge dosimeter allows for early detection of any potential radiation hazards and helps protect the pilot's health.

What is a biodosimeter?

A biodosimeter is a dosimeter used in biodosimetry - a device used to measure a dose of ionizing radiation.

Do dosimeter badges detect any exposure to alpha particles when worn by radiation workers?

Dosimeter badges typically do not detect exposure to alpha particles because alpha particles cannot penetrate the outer layers of the badge to reach the dosimeter inside. Alpha particles are stopped by even a thin piece of clothing or the dead layer of skin, so they are not typically captured by external dosimeters worn by radiation workers. Specialized internal dosimeters may be used to monitor alpha particle exposure if it is a concern in a particular workplace setting.

What is the detector of nuclear radiation?

A radiac detects nuclear radiation. There are many types of radiac, some are: Geiger counter, ionization survey meter, scintillation counter, film badge dosimeter, electroscope dosimeter, electrometer, drift meter, cloud chambers, etc.

What is pen dosimeter?

A pen dosimeter is a dosimeter the size and shape of a pen. In many cases they are radiation quartz fiber dosimeters made during the cold war for civil defense workers in the case of a nuclear attack. Of these the CD V-742 is the most common with over three million being produced.

Why is a noise dosimeter calibrated at 114dB?

There is no technical reason to calibrate a dosimeter at any one particular sound level, and dosimeters may be calibrated at a number of different levels. The important thing is that the calibration includes sound levels relevant to the noise that will be measured. One particular model of calibrator happens to produce a sound of 114 dB. Others use 93 dB and other levels
