[ RadSafe ] radiopharmacy dosimetry

Thu Mar 8 02:11:38 CST 2012

radsafers,
We operate a nuclear pharmacy and distributed to hospitals short-lived isotopes with half-life between 1 to 10 hours such as f-18, Tc-99m and Ga-68. There is an organized Dosimtry program for the nuclear pharmacy where we require employees to wear badges and carry out urine tests every three months as required by regulations in the country.
We also carry out hands-feet check at the end of each shift at the pharmacy.
In Case of failure, such as spilling large quantities of material, we, of course, will make an immediate urine test.
The problem is that because the short half-life of the isotopes, urine test, every 3 months, does not find out if employees breathed or swallowed radioactive material  that could risk them, in a process which regularly released to the workspace amount of material that are not appears in the environmental  detectors and testing of pollution that we perform regularly in the laboratory, but can still risk the workers.
The best solution was to perform urine tests or Whole Body Counter once or twice a day - something impossible in practice.
Can you tell me what is done in your country and is there a reference to the laws in your respective countries or international recommendations?
I would like to know what instruments you use for the area detectors, what you do with the workers and what is the period for internal dosimetry.

Thank you,

Y. G,

Senior adviser for radiation protection

Joe,
I am following those "genome" sensations hardly. I am not interested to know, when I will die of which cancer - are you? As long as there is no definite cure for "cancer" to prevent it, I do not care for it. I simply hope to live as long as possible, but under the condition that my brain works as well as it does now.

Best wishes for the future....

Franz

I believe that the simple answer is that both bombings were air bursts.  Technically, what this means is that the bombs exploded at a high enough altitude that the fireballs did not touch the ground. Therefore, there was much less (and much finer) debris and dust incorporated into the fireball, and the resulting fallout was more readily dispersed farther afield.

In contrast, a ground-level burst would be much different.  The local fallout plume would easily produce lethal doses many miles downwind of ground zero.

Subject: [ RadSafe ] Fallout

Dear members,

I am in need of clarification. Everything I've seen from the effects of the Hiroshima and Nagasaki detonations suggest that the initial burst of rad during the blast in the 3-km annulus around, but outside of, the blast zone caused the radiation-related cancers and deaths in the surviving cohort, and when I plot cancers, it is indeed linear with dose down to about 10 rem where it merges with background (Figure attached), but that fallout did nothing measurable. Is this correct? Is it because doses from fallout were so low?

Thank you,

Jim

Jim,
Recheck your selection of data on bomb-related cancer.
Breast cancer in women reciving 1-50 rad was significantly LESS
than "expected".

I would be dubious of any modeling program that claimed to answer this
without error bars larger than the predicted results.  The more
confident someone was that their program could model reality, the less
confident I would be that they had a clue.  Even if they were
breathtakingly convincing, I would want an extensive sampling program,
using long term kits and continuous radon monitors, to verify.

I have a project in which there are 6-8,000 release points which are
200m
radius central pivot spray irrigation systems.  The area is quite flat
with
only 30-50 meters of relief over 10s of kilometers. Given a 'Q' for each
release point and known atmospheric conditions, I'd like to calculate
the
average dose of radon & daughters being released.  The total release in
a
season is about 3-5 KCi of radon activity in an area about 3,000 km^2.
The
release is fairly uniform throughout the irrigated area.  Several
communities are present in the 'middle' of the irrigated area. Wind rose
is
well characterized and the vertical temperature change is uniform.
There
are seldom, if any, temperature inversions.  The typical radon
concentrations in the irrigation water are 1,500 -10,000 pCi/L. Outliers
may exceed 1 million pCi/L in the vicinity of a uranium feature.

Are their any 'magic bullets' already developed to handle this kind of
problem?
