How do you convert Sievert to Becquerel and mrem to picoCurie?

2.4 mSv converted to mrem?

The term mSv is a Millisievert and the term mrem is a Millirem, both used in radiation to measure a dosage. 2.4 mSv is equal to 240 mrem.

What is the annual occupational dose limit?

{| | |} the ICRP limits for occupational workers are 20 mSv (2,000 mrem) per year, averaged over defined periods of five years, with the further provision that the dose should not exceed 50 mSv (5,000 mrem) in any single year.

Is 0.3 a lot of radiation?

You need to specify the units used to take the measurement. It could be presented in Sv, Gy, rad or mrem. (So I am asking you 0.3 what??)Light radiation sickness begins at about50-100 rad0.5-1 gray (Gy)0.5-1 Sievert (Sv)50-100 rem50,000-100,000 mremSo if your measurement is in Rad - no it's not a lot. If it's in Gy or Sv then it is a significant dose, but will not cause acute sickness. If it's in rem then it's not a lot.

How much radiation is an average person in the USA exposed to each year?

According to NCRP Report #93, "Ionizing Radiation Exposure of the Population of the United States" (1987) the average exposure is about 295 mRem of Natural Background Radiation and about 63 mRem from Manmade Radiation (medical + consumer products) . Most (about 67%) of the natural background radiation is from inhaling Radon gas.

What is meant by the terms mCi and mrem?

Ci is abbreviation for curie, which is a unit of activity of radioactive substances equivalent to 3.70 × 10 10 disintegrations per second: it is approximately the amount of activity produced by 1 gram of radium-226. rem: the quantity of ionizing radiation whose biological effect is equal to that produced by one roentgen of x-rays. mrem is a millirem & mCi is a millicurie.

How many rads are in a dental X-ray?

The exposure one receives from a radiograph/x-ray at the dentist is dependent upon what type of x-ray is taken and how many. Dental x-rays of any kind are much safer/lower radiation exposure than most medical x-ray exposures, especially including CT scans. CT scan of your head ~ 200 mrem CT scan of the heart ~ 2,000 mrem Dental Bitewing ~ 0.5 mrem (you typically receive about the same or more radiation annually from living in the mountains (closer to outter space) compared to someone at sea level, as you do during a dental x-ray (both of which are typically less than a 1/6th your usual annual exposure to radiation from the environment).)

How much is too much radiation?

That is a very good question and not easy to answer. This will depend on the individual, the risk they are taking and the benefit that they will receive from it. As pointed out in the Radiation and Us page, we receive approximately 360 mrem of radiation every year. The legal limit imposed by the federal government in this country for an occupationally exposed worker is 5,000 mrem per year. If we look first at doses received in a short amount of time, (acute doses), the first biological effect begins to be able to be detected by laboratory analysis at 10,000 to 25,000 mrem. Actual immediate life threatening doses are limited to levels of 100,000 mrem and above. The life shortening doses may be lower than that, and are approximated by taking the data at higher doses where the effects are apparent and extrapolating the risk down to lower doses. Being conservative, the regulators use a model of a straight line from high doses down through the zero dose/zero risk point, so that any dose presents some small risk. Also you need to know that doses received over a longer period of time allows for repair of cells by the body, and presents less of a risk. See the Radiation and Risk page for more information. So to answer the question, the doses receive by the workers in nuclear power, an extra 100 to 5,000 mrem per year (average about 500 mrem), are seen by most scientific organizations as presenting a low risk compared to normal occupational hazards encountered during a working lifetime. Children, fetuses and embryos are more sensitive and have a longer expression time than adults, and so have smaller allowable doses. It is really a personal choice how much is too much. In some situations, such as to save someone's life, I personally would accept around 100 rem, but in the normal course of my work, I would rather keep my dose to less than 5 rem per year.

White radioactive labels on packages at an accident scene tell the responder?

The white radioactive labels mean that the intact packages have exposure rates under 0.005 mSv/hr (0.5 mrem/hr) on any outer surface of the container and do not present a great exposure risk.

Are dental implants necessary?

Dental implants are designed to restore the functionality and aesthetics of one or missing teeth. The more accurate answer would lie within your expectation of how important it is for you to have teeth. Dental implant is a wonderful invention that has helped humans restore their functionality and the esthetics in the best possible way

How do you convert mrads to mrems?

A rad measures the amount of radiation absorbed by a gram of material where as a rem measures the biological effects of different kinds of radiation. To measure the degree of biological effects produced by radiation you would need to know the mrad value as well as the type of radiation because different types of radiation produce different degrees of damage. For example every 1 mrad of beta or gamma radiation produces 1 mrem, every 1 mrad of high energy protons and neurons produce 10 mrems and every 1 mrad of alpha particles produce 20 mrems.

Is it true radioactive material and radiation are unnatural-they did not exist on earth until creatd by scientists?

Radioactive materials and radiation existed long before scientists. Radiation occurs naturals in the air we breath, in the food we consume, in the earths crust and in the water we drink. We in 3.5 million radioactive molecules every time we take a breath. In a about a year we consume 240 mrem of raditaion naturally from theses causes.

Does radiation affect the radiology technician's body?

The simple answer is yes, but the exposures the RT receives are monitored so that the RT doesn't approach what is considered by the radiation safety community to be hazardous levels of exposure. What the RT will probably receive is a chronic, low level exposure to radiation (unlike the acute, high levels that we hear about in radiation bombings, accidents, and poisonings). In the US, the whole body limit is 5000 mrem per year (50 mSv/yr). The RT typically never approaches this level of whole body exposure. The radiology area where the RT will get the most exposure is in the fluoroscopy suite, the nuclear medicine technologist in the PET imaging area, and the radiation therapist in the brachytherapy application. The RT should be schooled in the concepts of time, distance, and shielding in order to keep their exposures as low as reasonably achievable. The pregnant RT is limited even further, to 500 mrem/yr (0.5 mSv/yr). This is to protect the relatively radiosensitive fetus from undue exposure.
