How do you calculate the dose rate from an Am-Be neutron source?

neutrons are produced at a rate of 2.8x10+6 neutrons/second/curie Am-241 for an optimally, well mixed source of americium and beryllium.
the neutron dose rate of a one curie Am-Be source would be 34.7 mR/hr (or 347 µSv/hr) at 30 cm.
the gamma dose rate of a one curie Am-Be source would be 0.17 mR/hr (or 17 µSv/hr) at 30 cm.
americium-241 also decays by spontaneous fission with a half life of 2x10+14 years, producing 0.18 neutrons/second/curie Am-241. note that beryllium is not required for this neutron production mechanism.

How you can calculate the maintenance dose in the formulation of controlled release tablets?
Dt = Dose (1 + 0.693 × t/t1/2) Where, Dt = Total dose, Dose = Immediate release dose, t = Total time period for which sustained release is required, t1/2 = Half-life of drug.
How many protons and newtrons does a hydrogen atom contain?
There is one proton, one electron in hydrogen. The number of neutrons depends on the isotope of hydrogen. Hydrogen has three isotopes: protium, deuterium and tritium with 0, 1 and 2 neutrons respectively.
What does LD50 measure?
LD50 (short for lethal dose 50) is the dose of a substance at which it kills 50% of test subjects.
What is a sentence for the idiom like a dose of flakes?
I have never heard this. It's usually 'like a dose of salts', meaning fast and thoroughly. 'She arrived with a basket of cleaning supplies and went through the house like a dose of salts.'
What does boron make?
What dose the Boron do
How do you calculate the integral dose?
mean dose x mass = integral dose
How do you Calculate annual radiation dose?
There are various tools available that you can use to calculate your annual radiation dose. You need to provide the required values to get the dose.
What is unique about receiving a dose of neutron radiation and an equivalent dose of other types of radiation either ionizing or nonionizing?
The neutron radiation can turn stable elements in your body to radioactive isotopes (called neutron activation). This makes you radioactive in a way that cannot be removed by any attempt at decontamination. No other type of radiation can do this.
How many protons and neutrons dose fluorine have?
proton of fluorine is 9 and neutron is also 9
What is meant by supercritical andhow dose it relate to making a nuclear bomb?
subcritical - a mass or arrangement of fissionable or fissile material unable to sustain a neutron chain reaction. It can provide a fixed amount of neutron multiplication from a neutron source, but after removal of the neutron source the chain reaction rate drops exponentially.critical - a mass or arrangement of fissionable or fissile material capable of sustaining a constant neutron chain reaction. No increase or decrease. (Nuclear reactors operate at critical)supercritical - a mass or arrangement of fissionable or fissile material capable of not only sustaining a neutron chain reaction, but once initiated the chain reaction rate rises exponentially. (Nuclear fission bombs explode when made supercritical)A nuclear fission bomb must have 2 of these states: subcritical (so that it can't explode until desired) and supercritical (so that it explodes with an effective yield). This requires a rapid "assembly" system using conventional explosives to rearrange the fissile material from subcritical to supercritical in about 1ms. A neutron source starts the chain reaction and the explosion completes in about 1 microsecond.
How you can calculate the amount to administer?
I prefer to use the fractional proportion method: Desired Dose ----------------- X Dosage Unit = A Dose On Hand
How you calculate maximum daily dose?
maximum daily dose for a drug product is calculated based on clinical studies. To know a max. daily dose we can refer medsafe website. Generally this website is reliable.
How you can calculate the maintenance dose in the formulation of controlled release tablets?
Dt = Dose (1 + 0.693 × t/t1/2) Where, Dt = Total dose, Dose = Immediate release dose, t = Total time period for which sustained release is required, t1/2 = Half-life of drug.
What kind fo power source dose hovercraft used?
The manure. You can get it from the guy with the shovel.
What dose transmit mean?
Roughly "moved without loss from source to destination".
What is the formula you use to calculate drug calculations?
Which drug calculations? The toxic dose, the effective dose, the required dose, the metabolic halflife, the time since consuming and many more calculations require completely different formulae and data.
If an element has 12 protons and 13 neutrons how many electrons dose it have?
12 electrons. Remember, electrons and protons must be balanced in charge; neutron number may vary.
